Why compress images?
Oversized images are the #1 cause of slow websites, rejected uploads and full phone storage. A 6MB photo straight off a phone camera can usually shrink to a few hundred kilobytes with no visible difference — loading 10× faster and passing every upload limit.
Perfect for
- YouTube thumbnails — YouTube caps uploads at 2MB; a compressed JPEG sails through. (Researching designs? Use our thumbnail downloader.)
- Websites and blogs — smaller images mean faster pages and better Google rankings.
- Email attachments — fit under the 25MB Gmail limit with room to spare.
- Marketplace listings — meet strict photo size limits on Etsy, eBay and job portals.
Private by architecture
Most online compressors upload your photo to their servers. This one can't see your images even if it wanted to — the entire pipeline runs in your browser with the HTML5 canvas API. That's why it works instantly and even offline. Got a video that's too big too? The video compressor works the same private way.
Frequently asked questions
How much smaller will my image get?+
Typically 60–90% smaller at the default 80% quality, depending on the source image. Converting PNG screenshots to WebP or JPEG gives the biggest savings.
Is my image uploaded to your server?+
No — this compressor runs 100% in your browser using the canvas API. Your image never leaves your device, which also makes it extremely fast.
Which formats are supported?+
You can load JPEG, PNG, WebP and GIF images, and export as JPEG, WebP or PNG.
What quality setting should I use?+
80% is visually lossless for most photos. Go 60–70% for web images where size matters most, and 90%+ for print or portfolio work.
JPEG or WebP — which should I pick?+
WebP is ~25–30% smaller than JPEG at the same visual quality and works in all modern browsers. Pick JPEG only if you need compatibility with very old software.
Is there a file size or usage limit?+
Images up to 50MB work fine, and you can compress as many as you like — it’s free and unlimited.
