Under 50 KB means a maximum
The output can be substantially smaller than 50 KB; it is not padded to exactly the limit. Fylqen chooses the highest-quality feasible result within its bounded optimizer.

Compress an image under 50KB
Prepare a JPEG whose measured output is at or below 50 KB while keeping as much quality and dimension information as the constraints allow.
Start here: This page starts with a 50 KB maximum, not an exact target. Smaller verified files are valid.

How to use this page
Step 1
Select the source
Choose the image from your device and inspect its dimensions and current file size.
Step 2
Keep the maximum
Use Maximum mode with 50 KB, or edit the value when the destination uses a different limit.
Step 3
Verify quality and size
Process, review the actual measured output, and download only after the result passes the displayed checks.
When compression is not enough
If the original cannot meet the limit at the supported quality and resize bounds, the tool reports that clearly rather than producing an unverified file.
