About the Image Compressor converter

Set a target size in kilobytes and the compressor steps the quality down until the file fits, stopping as soon as it does so the image is never degraded more than necessary.

Upload forms with a 2 MB limit, email attachments and job application portals are the usual reasons people end up here.

Resize first, then compress

Dimensions dominate file size. Halving the width of an image removes three quarters of its pixels — a far bigger saving than any quality adjustment, and with much less visible damage.

Set a maximum width alongside your target size and the image is scaled down before compression, which lets the quality stay high.

When the target cannot be met

Quality has a floor. If the smallest acceptable encoding is still above your target, you get the smallest result achieved along with a note saying so, rather than a badly mangled image.

The fix is almost always to reduce the dimensions.

JPG or WebP

WebP reaches any given size at noticeably better quality and is supported by every current browser. Choose JPG when the file is going somewhere old or unpredictable — a print shop, a legacy CMS, an email client from 2015.

Frequently asked questions

Will PNG screenshots compress well?

Converting a screenshot to JPG usually makes text look fuzzy. Try WebP instead, or reduce the dimensions and keep it lossless.

Is compression reversible?

No. Lossy compression discards data permanently, so always keep your original.

Does it strip EXIF metadata?

Yes. Redrawing on a canvas drops EXIF, which removes camera details and GPS coordinates as a side effect — usually a welcome one before sharing a photo.
