Compress an Image to 50KB
This page uses the same browser compressor, with Custom Size already set to 50 KB. That is 51,200 bytes. Fifty kilobytes is a tight budget: a detailed photo often needs a smaller pixel size or a JPG or WebP export before it fits. The card shows the real compressed size. Target Achieved means the file is at or below 50KB. Target Not Achieved means it is still larger. Reaching 50KB is a goal, not a guarantee.

Low starts at 90%, Balanced at 75%, and High at 50%. These are encoder settings, not guaranteed file-size reductions.
Target size is on, so this slider and the presets do not control the final file. The compressor picks the highest quality that fits the target. Turn target size off to use this slider again.

Resize Image (Optional)
Change your image dimensions before compression. Keep the original size or enter custom dimensions.
Select an image to set its size. Resizing stays off until you enable it.
Add an image, then compress it.
How to work toward 50KB
Start with the original dimensions. If the shown size stays above 50KB, change one thing and compress again.
- 1
Add a JPG, PNG, or WebP image. Each file can be up to 20 MB. A flat icon and a busy photo do not use 50KB in the same way.
- 2
Leave Custom Size at 50. That entry is 51,200 bytes, because 1 KB is 1,024 bytes. Open Advanced Settings only if you want a different number.
- 3
Compress once with resizing off. The result lists the compressed size next to Target Achieved or Target Not Achieved.
- 4
If the status is Target Not Achieved, the number on the card is the real file size and it is still above 50KB. Do not download it as if it met the limit.
- 5
When a smaller picture is acceptable, turn on Allow resizing to reach target size, or type a width close to the size readers will see. Aspect ratio stays locked unless you turn that off.
- 6
For a photograph that is still too large, choose JPG or WebP yourself and compress again. A transparent PNG keeps every color, so it may not reach 50KB. The tool does not switch the format for you.
The homepage still starts with target size off. If 50KB removes too much detail, try compressing an image toward 100KB or compressing an image toward 200KB. The guide to reducing an image toward a size limit explains why the same picture can miss one budget and fit another.
Questions about the 50KB target
Why 50KB is difficult for some images, how to read the real file size, and when resizing or another format is worth trying.
No. The search keeps the highest quality it tried that is at or below 51,200 bytes. If none fits, the status is Target Not Achieved and the card shows the actual size, which can still be larger. Fifty kilobytes is a goal, not a guarantee.
