How do I compress an image?

Drop one or more images onto the page, pick a quality level, and the compressed versions are ready to download in seconds.

Does image compression reduce quality?

It does, but at quality 80 the difference is invisible to the eye for most photos while the file is roughly half the size. Use the before/after slider to verify before downloading.

Can I compress multiple images at once?

Yes. Drop a batch of files and they're all compressed together. You can download them individually or as a ZIP.

Which image formats are supported?

JPG, PNG and WebP. PNG transparency is preserved, and animated GIFs are passed through unchanged.

Will EXIF data be removed?

By default, EXIF (camera info, location) is stripped to reduce size and improve privacy. Toggle "Keep EXIF" to preserve it.

Is there a file-size limit?

No fixed limit. Compression happens on your device, so the practical cap is your device's memory.

Are my images uploaded?

No. Compression runs entirely in your browser — your images never leave your device.

How do I compress images for a website?

Aim for a quality of 75–80 and a max width of 1600 px for hero images, 800 px for thumbnails. Save as WebP for the smallest size.

Can I compress images on iPhone or Android?

Yes. Open the page in your phone's browser, pick the photos, and the compressed copies are saved straight to your downloads.

Is the image compressor free?

Yes — no signup, no watermark, no quality cap.

Good to know

Image weight is the single biggest lever on how fast a web page feels, and most compression wins come from two settings working together: quality and dimensions. Re-encoding a photo at quality 80 typically halves its size with no visible difference, but the bigger saving is often resizing — a 4000-pixel phone photo displayed in an 800-pixel column is carrying five times the pixels it will ever show.

Format choice compounds this. JPG suits photographs, PNG is for flat graphics and transparency, and WebP usually beats both. A useful workflow for the web is to compress here and then convert the result with Convert to WebP, or resize first with Resize Image before compressing so you are not spending bytes on pixels nobody sees.

Watch the EXIF toggle. Camera files embed metadata — GPS coordinates, device model, timestamps — that inflates the file and can leak where a photo was taken. Stripping it (the default) is both smaller and more private; keep it only when you genuinely need the capture data. Use the before/after view to confirm your eyes agree with the number before you commit to a quality level.
