Can I resize an image to exactly 100KB?
Yes. Resize Relay adjusts compression quality and dimensions to get as close as possible to a strict 100KB target.

FAQ
Which format is best for a 100KB limit?
JPEG or WebP usually works best for tight size limits. PNG is lossless and may remain above 100KB.
Are my images stored?
No. Images are processed in-memory and are not retained after processing and download.
Common situations for this workflow
Government or school forms that reject files over 100KB.
Profile photo uploads where the portal enforces a very small image limit.
Legacy systems that accept only low-size JPG images for final submission.
Checklist before you upload
Start with JPEG unless the destination explicitly requires PNG.
Reduce image dimensions if compression alone cannot reach 100KB cleanly.
Check both the final file size and the final format before uploading.
Tips to hit the target faster
100KB is a tight limit, so simple backgrounds and cropped portraits compress more reliably than busy scenes.
If the source is a large phone photo, downscaling resolution usually matters more than small quality tweaks.
When an upload system is strict, target slightly under the limit rather than right at 100KB.
