Private: Compression stays in your browser — files never upload.

How to verify no upload
  1. Open DevTools (F12 or ⌥⌘I) → Network tab.
  2. Drop images and wait until outputs are ready.
  3. Confirm there is no image POST/upload — only the page and scripts load.

“Try sample” may fetch a public demo from this site — that is not your file upload.

Honest limit: huge megapixel images can use a lot of RAM. Prefer batches of reasonable size; processing never leaves this tab.

Ready — drop JPG, PNG, or WebP.

How to compress or resize images

  1. Drop one or more JPG, PNG, or WebP files onto the film frame (or click Choose).
  2. Pick Compress, Resize, or Social crop. Processing runs in your browser — files are not uploaded.
  3. Download each file, or Download ZIP for a batch.

Who it’s for

Anyone who needs images under a size limit for forms, email, or social — and prefers a private tool with no account over a cloud upload.

FAQ

Do my files leave my device?

No. Compression, resize, and crop run in your browser. We only serve the page — your images are never uploaded for processing.

What formats are supported?

JPG/JPEG, PNG, and WebP as inputs. Output JPG, PNG, or WebP. HEIC is handled by HeicLocal; WebP↔PNG by WebpKit (linked in the footer).

Is there a file limit?

No cloud quota. Very large images may hit browser memory limits — try fewer files or smaller dimensions if the tab struggles.

Is SquashImg free?

Yes. Free forever — no account, no paid plans, no ads.
