Image Compressor
Camera files are heavy. Shrink them for your website, email or clients — with a quality slider so you stay in control of the trade-off. Everything happens on your device: nothing is uploaded, ever.

JPG, PNG or WebP · batch friendly · nothing is uploaded
Changing settings re-applies to new files you add. PNG files ignore the quality slider (lossless).
Why compress your photos?
A modern camera happily produces 8–15 MB JPEGs. That is wonderful for printing and miserable for everything else: websites load slowly (and Google ranks them accordingly), email providers reject attachments, and clients on phones burn data plans downloading a portfolio. Compression removes data your viewers cannot see — at sensible settings, a photo that was 6 MB becomes 900 KB with no visible difference on screen. If you are preparing images for the web, pairing this tool with the resizing option (1600 px is plenty for a full-width blog image) gets most files under 300 KB.
JPEG, WebP or PNG — which should you choose?
JPEG remains the safe default for photographs: every device opens it. WebP is usually 25–35% smaller than JPEG at the same quality and is supported by all modern browsers — our choice for websites. PNG is lossless and therefore large; keep it for graphics, screenshots and images with transparency, not for photos. If you shoot for clients, deliver JPEG; if you publish for the web, deliver WebP and keep the original somewhere safe.
What settings should I use?
For photos on a website, quality 75–85% in WebP or JPEG is the sweet spot. For email, cap the width at 1600 px as well. For a portfolio where quality is the product, stay at 88–92% and skip resizing. And whatever you choose, keep your originals untouched — compression is one-way. The workflow pairs naturally with the editing stage: pick your keepers in one of the free editing apps we tested, export, then compress the exports here. Technique still matters more than file size, of course — a small blurry photo loses to a big sharp one, so it is worth mastering how to take sharp photos every time before you worry about kilobytes.
Frequently asked questions
Are my photos uploaded to a server?
No. The compression runs in your browser using its built-in image engine. You can verify it: load this page, switch your device to airplane mode, and the tool still works.
Does compressing remove EXIF data?
Re-encoding through the browser strips most embedded metadata, including GPS coordinates — a quiet privacy bonus. Our dedicated EXIF viewer (arriving in Wave 1) will let you inspect exactly what a photo carries before you share it.
How many photos can I compress at once?
As many as your device can hold in memory — batches of 50 are routine on a laptop. Use “Download all” to receive them as a single ZIP.
Shooting video as well as stills? File discipline matters there too — see our guide to the best cameras for YouTube vlogging for the bodies our readers ask about most.
