How small should files get?
Custom settings activeThe tool finds the highest quality that still meets the target size, and scales down only if needed. Images already under the limit are left unchanged.
How it works
Step 1 · Add files
Drop images — 50KB target is pre-set on this page.
Step 2 · Confirm settings
Wait for local processing to finish.
Step 3 · Download
Download files under the limit, or Adjust one image that missed the target.
When you need 50KB
Some chat avatars, legacy forums, and old government forms still cap near 50KB — tighter than 100KB pages.
If you cannot hit the target
Lower max width aggressively (for example 400–800px), use JPEG or WebP, and avoid PNG for photo-like images.
Good for
- Legacy forum avatars and very old upload forms
- Chat or badge images with a tiny cap
- Thumbnail-sized photos where 100KB is still too large
What to watch for
Phone photos rarely fit under 50KB at full resolution. Drop max width to roughly 400–800px and use JPEG or WebP before expecting the target to hit.

Frequently asked questions
Is 50KB always reachable?
Not at full phone resolution. The tool lowers quality and scale to approach 50KB; very detailed photos may need a smaller max width first.
Are files uploaded?
No. Compression runs in your browser only. See the Privacy page for how local processing works.
50KB vs 100KB — which page should I use?
Use 50KB when the form explicitly caps near fifty kilobytes. Use 100KB or 200KB when you have a little more room.
Can I batch-compress to 50KB?
Yes. Process several images locally, then download each file or grab all results as a ZIP when they meet the limit.
