What Is Bulk Image Compressor (imagecompressr.com)?

Updated

Bulk Image Compressor is a browser-based batch image compression tool at imagecompressr.com. It compresses JPG, JPEG, PNG, and WebP files in bulk, and according to the site, the images are processed locally — "No uploading. No signup." — so files stay on your machine. It fits you if you need to shrink many images at once (for the web, email, or storage) without installing software or creating an account. It is not a full photo editor, and it is not a lossless compressor — the site states the algorithm is not lossless, though you can push quality to 95%+ for near-lossless results.

What it does

Batch size "Unlimited images," drop a massive number at once
Processing In-browser; images stay on your machine
Signup Not required
Typical result Size reduced "from MBs to KBs"
Usage claim 2 million+ images compressed per month

The site frames itself as a photo compressor for large batches — drop in "all the pictures of your favorite memories" and get a drastic size reduction.

How to compress images

  1. Drag your images into the dropbox (or use "Select files"). You can drop many at once.
  2. Optionally open Advance Settings to set Quality (%) and Max Size.
  3. Click Start Compressing (the button reads "Start compression with default settings" if you skip settings).
  4. Download the compressed images.

Expected result: your images come back smaller, often dropping from megabytes to kilobytes.

The two controls that matter

  • Quality (%) — controls how much compression is applied. The site notes the algorithm is not lossless, but selecting 95%+ quality gives near-lossless results. Lower values shrink files more aggressively.
  • Max Size / target size in KBs — lets you aim for a specific file size. Drop all images, select the target size in KBs, and get new images at that reduced size.

There is also a resize option: set a max target width and height in pixels (for example, 512) to bring every image within that range — useful when you need all images under 512×512.

Pricing: free tier and one-time payment

The site states your first 100 images are free. Beyond that, unlimited compression is available with a one-time payment of $10 — "No subscription, yours forever." If you have already purchased, you enter the email used at purchase to unlock it. The site lists a "Buy ($10)" option; no subscription or recurring billing is mentioned.

When to use it — and when not to

Use it if:

  • You have a large batch of JPG/PNG/WebP files to shrink at once.
  • You want no signup and no server upload (privacy-sensitive images).
  • You need to hit a target file size or a max pixel dimension.

Look elsewhere if:

  • You need truly lossless compression — the site explicitly says its algorithm is not lossless.
  • You need formats outside JPG, JPEG, PNG, and WebP.
  • You need editing features beyond compression and resizing.

Common questions

Is it good for photos? The site positions it as a photo compressor and claims strong size reductions on personal photos.

Does it upload my images? No — the site says images stay on your machine and are not uploaded.

Do I need an account? No signup is required to start; the first 100 images are free.

How do I get near-lossless results? Set quality to 95% or higher.
