How the 600 KB limit is reached
PhotoReducer tries different quality levels and keeps the best one whose file stays under 600 KB. Most photos reach this limit through compression alone, keeping their original dimensions.
Who asks for 600 KB files?
Newsletter platforms like Mailchimp and Substack flag campaigns as heavy once embedded images stack up, and 600 KB per photo keeps a photo-rich issue from tripping spam filters. Photographers uploading gallery previews to Squarespace or Behance also land in this range before the full-resolution version is available on request.
Frequently asked questions
Will the image still look good at 600 KB?
At this size the difference from the original is usually invisible on screen — most photos keep their full dimensions.
Does it change the format of my file?
The output is JPG by default — the format virtually every form accepts — and you can switch to WebP. JPG, PNG, WebP and AVIF are accepted as input.
Is my photo uploaded anywhere?
No. Everything runs locally in your browser with WebAssembly — your image never leaves your device, which makes this safe even for ID photos and documents.
