Image Compress

Recompress to a target quality. No upload, no quality cliff.

How it works

Reduce image file size for email attachments, web pages, or storage without uploading anywhere. Quality 75 is a good default — visually almost identical to the source for most photos but typically 50–70% smaller. Lower the slider further if you need a strict size budget.

Verify it yourself. Open DevTools → Network → run a conversion. The only requests you'll see are the page assets — your file never leaves this tab.
On mobile? Downloaded files save to your Files app (iPhone/iPad) or Downloads folder (Android), not your photo library. To move an image to Photos, open it from Files and tap the share button, then "Save Image." This is how all browser downloads work — not a Bytario limitation.

FAQ

What quality value should I use?

85 is "imperceptible loss" for most photos. 75 is "noticeable on close inspection but fine for social/web". 60 is "obvious artifacts" — use only if you need tiny files.

Why is my PNG still huge after compression?

PNG is lossless, so quality re-encoding does almost nothing. Convert PNG → WebP (or JPEG if there is no transparency) for real size reductions.

Does this strip metadata too?

Yes — the decode/re-encode round trip strips EXIF, IPTC, and XMP as a side effect. Use this tool for both compression and metadata removal in one step.
