This page opens the compressor with 50 KB selected. A phone photo is usually reduced in pixel dimensions as well as quality, so its width and height drop along with the file size. Each photo keeps the highest quality the limit allows, and the saved copy ends close to 50 KB.
Check the copy at the size it will be shown. If the pixel size is too small for where it goes, pick a larger limit such as 500 KB and compare the two results.
How to compress a photo to a target size
- Drop one or more photos onto the box (or tap it to choose).
- Pick the maximum size the website or form allows.
- Download each photo, or all of them as a ZIP.
Questions
Why are the pixel dimensions smaller than my photo?
The tool lowers quality first. If even low quality is still over 50 KB, it reduces the width and height a little at a time until the file fits.
Is the 50 KB limit for each photo or the whole batch?
Each photo. Every file you drop in is compressed against the same 50 KB figure. Download them one at a time, or all together as a ZIP.
Will my photos be uploaded?
No. The compression runs in your browser with the canvas API. Your photos never leave your device, which is also why it is fast.
How does it hit an exact size?
It tries different quality levels (a binary search) until the file is just under your target. If even low quality is too big, it also reduces the pixel dimensions a little at a time.
Why did my PNG turn into a JPG or WebP?
PNG is lossless, so it cannot be squeezed to a target size. Photos are re-encoded as JPEG. Images with transparency become WebP so the transparent areas survive; where your browser cannot save WebP, they become PNG instead.
Is the location data removed?
Yes, from every re-encoded photo: drawing it on a canvas leaves out its GPS location and camera details. With Best for each photo, a photo already under your limit is handed back unchanged and keeps its metadata. Use Remove photo location for that.
