About this tool: Free Image Compressor
Reduce image file size locally in the browser before uploads, review threads, screenshots, and final exports. No upload required — everything runs locally in your browser for privacy and speed.
Common use cases
- Quality 70-80 is usually enough for review links and docs.
- Set a max width to slim down oversized screenshots or product stills.
- Everything stays inside your browser.
Compressing an image without wrecking it
Compression is the single easiest page-speed win: most photographs are shipped at several times the size the screen can even show. Compress to the dimensions you will display, then to the quality that still looks clean.
Compressing in the right order
- 1
Resize first, then compress
A 4000-pixel photo shown in a 800-pixel column wastes four fifths of its bytes no matter how well it is compressed.
- 2
Compare at 100 percent zoom
Compression damage is invisible in a scaled-down preview and obvious at real size. Judge it at the size it will be seen.
- 3
Keep the original
Compression is lossy and one-way. Archive the source file and compress a copy for delivery.
Image compression questions
- How much can I compress without it showing?
- It depends on the content: smooth gradients tolerate far more than fine texture. Measure at realistic display size rather than trusting a number.
- Does compressing lose quality permanently?
- Yes, for lossy formats. Keep the original and treat the compressed file as a delivery artefact.
- Is compression local?
- Yes, and it is free — nothing is uploaded and no credits are spent.
