Some portals have very strict size limits. Compressly can aggressively reduce size using a combination of downscaling and quality adjustments. Follow these steps.
How to compress to 50 KB
- Open Compressly and choose your image (use JPG if possible).
- Enter 50 in Target (KB) and set output to JPG or WebP.
- Use quality 0.6 or lower if needed; try reducing target to 45 KB if initial result is slightly above 50 KB.
- If target still not reached, reduce pixel dimensions slightly (downscale to 800–1000 px on the longest side).
Tip: Small images lose fine details. Always keep a backup of the original file. If the
portal allows, try WebP for smaller size and better visual quality.

A: At 50 KB some quality loss is inevitable. Balance quality and size by experimenting
with target KB and small downscales.
Q: Which format is best for tiny sizes?
A: WebP tends to be the smallest. JPEG at low quality is the next best option. PNG is
