What is Bulkr?
Bulkr is a desktop application for Mac and Windows that backs up, browses, and downloads photos and videos from Flickr. It is aimed at people who want a local copy of their own Flickr library, or who need to pull down large numbers of images from other public sources on the service. The free version covers the core job; a paid PRO tier is offered for heavier use.
What it actually does
According to the site, Bulkr can:
- Back up your photostream and videos with a single click
- Download your own sets (albums) or any other user's sets
- Download photos in four different sizes
- Write title, tags, description, and geotag data into EXIF/XMP
- Preview images before downloading
- Auto-resume a download if the connection breaks
- Download Creative Commons photos and videos, up to 500 at a time, from Flickr search, your photostream, another user's photostream or set, your favorites, any Flickr group, or Explore
The EXIF/XMP writing is the detail worth pausing on. If you download a full-resolution file that has lost its caption and tags, you keep the picture but lose the context. Embedding that metadata means your local library stays searchable and sortable in tools like Lightroom or Apple Photos, rather than becoming a folder of anonymous files.
Who it suits
The strongest fit is someone with a large existing Flickr archive who wants an offline backup without clicking through albums by hand. A photographer who has years of sets and videos on Flickr, for example, could run a backup once, then re-run it periodically to pick up new uploads. The bulk Creative Commons download is a different use case: designers, teachers, or researchers assembling reference or public-domain material at scale, where grabbing 500 items at a time matters more than one-off saving.
The trade-offs are the usual ones for a desktop downloader. It is a separate install rather than a browser-based tool, so it is tied to one machine, and very large libraries will consume real disk space once full-size files and videos are included. Anyone who only needs a handful of images occasionally will find Flickr's own interface sufficient.
A practical next step
Install the free version and test it on one small set before committing to a full backup. Check that the downloaded files open correctly, that titles and tags came through as expected, and that the sizes you chose are the ones you actually want. If that test run behaves well, move on to your full photostream. If you need the higher-volume or PRO-only capabilities, compare the two tiers on the site's PRO page before deciding.
How do I back up my entire Flickr photostream with Bulkr?
Bulkr is a desktop application for Windows and Mac that backs up, browses and downloads photos and videos from Flickr. For a full photostream backup, the intended workflow is: install the app, connect it to your Flickr account, choose your own photostream, and start the backup. The page describes a one-click backup of your photostream and videos, which is the core of what you are asking for.
What the backup covers
- Your own photostream, including videos.
- Sets (albums) belonging to you or another user.
- Photos in four different sizes.
- Titles, tags, descriptions and geotags written into EXIF/XMP metadata, so the downloaded files keep their context rather than becoming anonymous image files.
- Auto-resume if the connection drops, which matters for a library of thousands of items.
Practical steps
- Install the free desktop app and sign in to Flickr through it.
- Select your photostream as the source rather than a set, group or favorites list.
- Pick the download size. Full-size gives you the archival copy; smaller sizes are faster and lighter if you mainly want a browsable local set.
- Enable metadata writing if you want titles, tags and geotags preserved in the files.
- Start the download and let it run. If your connection is unstable, the auto-resume behavior should let it continue rather than restart.
Free vs PRO
The site separates a free install from a PRO tier, with PRO presented as the way to "do more." The page does not state which specific limits apply to the free version, so treat the free tier as the way to test the workflow on a small set before committing to a large backup. If you have tens of thousands of photos, check the PRO page for the exact feature differences before starting.
A realistic scenario
Someone with a decade of Flickr uploads — several thousand photos across dozens of albums — would typically run the photostream backup first for the complete archive, then separately download individual sets if they want those folder structures preserved. The auto-resume and metadata features are the two that matter most at that scale; the four-size option is useful mainly if you want web-ready copies alongside originals.
One thing to plan for
A desktop download is not the same as an independent offsite backup. Once the files are local, copy them to a second drive or a cloud storage service so a single disk failure does not undo the work. Flickr's own export tools are another route worth comparing; see Flickr for the account-level options, and Bulkr for the desktop app itself.
Can I download photos and videos from other users' Flickr sets or groups?
Yes. Bulkr is built to pull media from Flickr beyond your own photostream, including other users' sets and group pools. According to its page, you can download your or any user's sets (albums), any Flickr group, favorites, explored photos, and creative-commons items, with photos and videos both supported.
What that looks like in practice
- Other users' sets: Point the app at a public set and download the whole album rather than saving images one by one.
- Groups: Download from a group pool, which is useful for archiving a community project or researching a theme.
- Favorites and Explore: You can also grab items you have favorited or photos surfaced in Flickr Explore.
- Bulk limits: The page mentions creative-commons downloads of up to 500 at a go from search, photostreams, sets, favorites, groups, and Explore.
- Formats and metadata: Photos can be saved in four different sizes, and title, tags, description, and geotag can be written to EXIF/XMP. Videos are downloadable too.
Audience and trade-offs
This suits people who want a local backup of Flickr material they don't own, such as researchers, archivists, or group moderators. The trade-off is that downloading someone else's work doesn't transfer rights: public availability on Flickr is not the same as permission to republish. Treat downloaded sets as an archive for personal reference unless the license or the owner says otherwise.
Bulkr is a desktop app for Mac or Windows, and its page notes it uses the Flickr API without being endorsed by Flickr, so very large jobs depend on API access and connection stability. The app advertises auto-resume if a download breaks, which matters for big sets.
A sensible next step: test with one small public set from another user, confirm the size and metadata options you want, then scale up. If you need a second tool for comparison, Flickr itself offers native download options for some albums, though not the same bulk flexibility.
What is the difference between the free version and Bulkr PRO?
Bulkr's free desktop app covers the core job of downloading from Flickr; PRO is aimed at people who want to do that at scale or keep their existing Flickr metadata attached to the files. The site itself only links to a PRO page without listing the exact feature split, so treat the distinction below as a general pattern for this kind of tool and confirm the current comparison on the PRO page before buying.
The practical difference usually comes down to three things:
- Volume and batching. Free downloaders typically cap how many photos you can pull in one session. If you are archiving a photostream of a few hundred images, that is workable. If you are pulling 10,000 full-size photos or a whole group pool, a cap becomes the deciding factor.
- Metadata handling. The site advertises writing title, tags, description and geotag into EXIF/XMP. That matters if you want the files to remain searchable and self-describing after they leave Flickr. Free tiers often strip or skip this.
- Convenience features. Auto-resume on a broken connection, downloading in four different sizes, and previewing before download are listed on the main page, but it is not clear which of these are free and which are PRO.
Who should care
A casual user who wants a copy of their own photostream, or a handful of Creative Commons images for a project, is probably fine with the free version. A photographer migrating off Flickr, a researcher building a reference library, or anyone downloading other users' sets and favorites in bulk is the natural PRO buyer — the value is in not babysitting a stalled download.
How to decide
Check the PRO page for the specific limits on batch size and whether EXIF writing is included free. If the free version caps you below your actual library size, or drops the metadata you need, PRO is the honest choice rather than a nice-to-have. The site reports over 749 million photos downloaded, which suggests the tool handles large jobs, but that figure says nothing about which tier those users were on.
For a second opinion on Flickr-specific download workflows, the official Flickr help pages at Flickr describe what the platform itself allows, and ExifTool is the standard reference if preserving metadata in your downloaded files matters to you.
How does Bulkr handle EXIF and XMP metadata when downloading Flickr photos?
Bulkr writes Flickr's title, tags, description and geotag data into the downloaded file's EXIF/XMP metadata, so that information travels with the photo instead of staying behind on Flickr. According to the site's own feature list, this is a built-in part of the download process rather than a separate step you configure afterwards.
What this means in practice
Metadata handling matters most when you are pulling a large archive off Flickr and want the files to remain searchable and self-describing on your own drive. If you download a 3,000-photo photostream without metadata, you end up with a folder of images whose titles, tags and locations exist only in Flickr's interface. With EXIF/XMP written in, tools like Lightroom, Apple Photos, digiKam or a desktop search index can read those fields directly.
The specific fields Bulkr states it writes are:
- Title
- Tags
- Description
- Geotag
Because geotags are included, location-aware applications and map views in photo managers will place the images correctly without manual work.
A concrete scenario
Suppose you maintain a Flickr account for a small gallery or a personal travel archive and want an offline copy you can search by keyword. You download your sets, and Bulkr embeds each photo's Flickr tags into the file. Later, you search your local drive for "harbour" or "2019" and the right images surface, because the tag lives in the file rather than in a web page. The same applies if you are backing up someone else's Creative Commons photostream for a project: attribution and descriptive tags stay attached to the image.
Trade-offs to weigh
- Embedded metadata increases file size slightly and, if you later re-edit and re-export, some editors may strip or rewrite fields. Check your export settings if metadata preservation matters.
- Geotags in files can reveal locations if you share those files publicly. Strip them before posting if privacy is a concern.
- Metadata is written at download time from Flickr's records. If a photo's Flickr title or tags are inaccurate or missing, the downloaded file inherits that gap.
Next step
Before committing to a large backup, download a small set of ten to twenty photos and open one in your photo manager or an EXIF viewer to confirm that title, tags, description and geotag appear as you expect. That single test tells you whether Bulkr's metadata handling fits your workflow better than a plain image download. For comparison, Flickr's own bulk download options and general-purpose downloaders are alternatives, though metadata behaviour varies between them, so verify each one the same way.
What should I do if a large download gets interrupted or fails?
If a large download stops partway, the first thing to check is whether the tool can pick up where it left off rather than starting over. Bulkr's page lists an "auto resume download if connection breaks" feature, so the practical move is to retry the same download and let it continue, instead of deleting the partial files or re-queuing everything from scratch.
A simple recovery routine
- Don't clear the download folder. Partial files are what a resume depends on. Deleting them usually forces a fresh start.
- Re-run the same job. Reopen the same set, album, photostream or group download and let it continue.
- Narrow the batch if it keeps failing. Downloading in smaller chunks (for example, one set at a time instead of an entire photostream) makes a failure cheaper to recover from.
- Check your connection and disk space. Interruptions often trace back to a dropped Wi-Fi connection, a sleeping laptop, or a full drive.
- Verify what actually arrived. Compare the number of files in the folder against the number of items in the album before assuming the job finished.
Why large jobs fail differently from small ones
A 20-photo download rarely exposes a problem. A 10,000-photo job runs long enough to hit network drops, sleep states and rate limits. One user quoted on the site, Peter Van Dijck, specifically noted that it was "the only app I tried for downloading 10,000 full-size photos that didn't crash on me" — a reminder that stability under long runs, not speed on small jobs, is the real test.
Two trade-offs are worth knowing. Resuming is faster and saves bandwidth, but it depends on the app correctly tracking which files are already complete. Starting over is more predictable but can take hours on a large photostream. If a job has failed repeatedly at the same point, a clean restart of just that portion is often quicker than fighting the resume.
If you're choosing a tool for this
Ask one question before committing to a big backup: what happens when the connection drops at photo 7,000? A downloader without resume support turns every interruption into a full restart. For anyone backing up years of Flickr content, that single behaviour matters more than interface polish.
Bulkr runs as a desktop app on Mac and Windows and is intended for backing up photostreams, videos, sets, favourites and group or explored photos. You can see the current feature set at Bulkr.
