Image Compressor
Format + quality + target-size binary search, before/after.
How to use
Choose images in Image Compressor: set Format, Quality, Max width px (0 = keep) and Target KB (0 = off), press Run, and PixelFlow processes the selected file in your browser with a Canvas and Web Worker pipeline — progress and cancel are available where supported. You get a result and a download when processing succeeds; the selected file is not sent to a Tolari processing endpoint.

- Set Format, Quality, Max width px (0 = keep) and Target KB (0 = off) images.

FAQ
Is Image Compressor really free?
Yes. No account or credits are required, and no paywall blocks the task. Browser, device, and stated file-size limits still apply. Ads may appear only when configured and enabled after the required consent signal.
Do I have to upload my files to use Image Compressor?
No. This tool reads and processes the selected file in your browser with a Canvas and Web Worker pipeline; the implemented flow does not send it to a Tolari processing endpoint. The page may still request scripts or other resources from configured third parties.
What should I enter in "Format"?
Put your format here — for example: jpeg. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.
How should I compare Image Compressor with other options?
Compare supported inputs, output quality, file-size limits, browser compatibility, and privacy terms using the same sample. Provider features and terms can change; check their current documentation.
How accurate is Image Compressor?
