Compress many photos at once, or convert them to JPG, PNG or WebP, with optional resizing.
Everything runs locally in your browser, so your photos are never uploaded.
Runs entirely in the front end. No sign-up, and your photos are never collected.
Every compression and conversion runs in your browser using the Canvas API. Your photos are never uploaded to any server, so internal images and client material stay private.
Drop a whole folder of photos in. Each one shows its before and after size with the saving percentage, and you can download them one by one or all together.
JPG, PNG and WebP convert freely. When a PNG becomes a JPEG, transparency is filled white automatically so it does not turn black.
Set a maximum edge length and bring 4K photos down to shop-ready sizes. High quality resampling keeps lines crisp.
At quality 80 the difference is almost invisible to the eye, yet files are typically less than half the size. If a photo contains a lot of text, fine detail or is destined for print, raise the quality above 90. Lower quality means smaller files but also more visible blocking.
Input covers JPG, PNG, WebP, GIF and most image formats your browser can display. Output can be JPEG, PNG or WebP. Note that an animated GIF keeps only its first frame after processing; still images are unaffected.
There is no hard limit, but selecting a very large batch (say more than 100) will use more memory. Around 20 to 50 per batch is a comfortable range.
No. The entire compression runs inside your browser and our server only delivers the static page. You can confirm this by opening your browser developer tools and checking the Network panel: no request is made during processing.
The JPEG format itself does not support transparency. Transparent areas must be filled with a colour, and this tool fills them white by default. Choose PNG or WebP output if you need to keep transparency.
No. JPEG and WebP are lossy, so the discarded detail is gone. Keep the original file and use the compressed version only for uploading or sending.
Shop listings, event photos, client deliverables. We can build an automated pipeline that compresses, renames, watermarks and files everything in one pass.
