Compress JPG Photos
Phone photos are often several megabytes, far bigger than an email, website or form needs. Shrink them with the quality slider, or ask for a specific size such as 200 KB. The photo is re-encoded by your own browser and never uploaded.
Your image is processed by your own browser and never uploaded. Many online editors send your photo to their servers and delete it later — this one never receives it at all.

Compress JPG: frequently asked questions
How much can I compress a JPG?
Most phone photos shrink by more than half at quality 60–80 with no visible difference on screen. The size comparison shows exactly how much you saved before you download.
Does compressing a JPG again reduce quality?
Every JPG save discards a little detail, so compress from the original photo rather than an already-compressed copy, and avoid compressing the same file over and over.
Quality or target size — which should I use?
Use Quality when you care most about how the photo looks, and Target file size when a form or site has a hard limit. Both show the final size before you download.
Can I compress several photos at once?
Yes, with Pro or Lifetime: add up to 100 photos and compress them in one batch. On the free plan you can compress one at a time, 5 times a day, with no account.
Are my photos uploaded?
No. Compression happens in your browser, so your photos stay on your device.
