Compress Image to 50KB
Balance a compact 50KB goal against quality and dimensions with a bounded, transparent browser search.
Category: compression · Priority: P1
Static JPG/JPEG, PNG, and WebP. Animated WebP is rejected. Processing stays in this browser.
How to target 50KB
- Choose one supported image.
- Keep the 50,000-byte preset or edit it, then choose a mode and format.
- Verify actual output bytes and download only after reviewing the result status.
A compact target with visible tradeoffs
50KB may preserve moderate detail in JPG or WebP, while complex lossless PNG files can require proportional resizing.
Quality first, dimensions only when allowed
Strict searches quality before dimensions. Keep dimensions finds the closest same-size result and marks it above target when necessary.
Format-specific behavior
JPG and WebP search quality 10–100. PNG runs lossless OxiPNG without invented quality controls or palette loss.
Verified rather than estimated
Every reported size comes from an encoded Blob, and no more than 32 candidates are created.
No image upload
The Worker or controlled fallback processes the image entirely in this browser.
50KB compression FAQ
What counts as reaching 50KB?
The verified Blob must be 50,000 bytes or smaller.
Can I prevent resizing?
Yes. Choose Keep dimensions; the result may be above target and will be labeled accordingly.
Does WebP transparency survive?
Yes when WebP or PNG is selected. JPG uses the visible background you choose.
Is anything stored?
No image or candidate is written to persistent browser storage.
