How to

  1. Drop or select your images — JPEG, PNG, WebP, GIF, BMP, ICO, AVIF and more are read straight away.
  2. Adjust the quality slider, and pick an output format if you want one; results update as you move them.
  3. Download each file from its row, or all of them as one ZIP.

FAQ

Are my images uploaded?
No. Compression happens entirely in your browser; nothing is sent to any server.
Which formats can I open?
JPEG, PNG, WebP, GIF, BMP, ICO and AVIF work in every modern browser. HEIC, TIFF, JPEG XL and JPEG 2000 depend on the browser — Safari reads them, Chrome and Firefox mostly do not. A file yours cannot read fails on its own row and the rest of the batch still runs.
Can I compress a PNG?
Yes. PNG is lossless, so saving a PNG back as PNG ignores the quality slider — to make it smaller pick WebP, which keeps transparency, or JPEG when the image has none.
What format do I get back?
“Same as input” keeps the original format whenever your browser can write it, and otherwise picks the closest one it can: a HEIC photo becomes JPEG, a GIF or BMP becomes PNG. You can also force JPEG, PNG or WebP.
What happens to animated GIFs or WebP?
Only the first frame is processed — the result is a still image.
