Private, exact-size compression
Compress image to 50KB
Create a clear file under 50KB without uploading personal photos or guessing at a quality slider.
Exact-size image compressor
Browser-only processing · six output formats
Your images never go to an upload server. Decoding, compression, previews, and ZIP creation happen on this device.
Advanced settingsDimensions, crop, quality
Dimensions never upscale. JPEG and BMP replace transparency with white. GIF output is static; animated GIF and WebP inputs use the first decoded frame.
A real before-and-after example
See what the size limit changes
This example starts as a detailed 3.30MB PNG and is processed by the same browser workflow used above. Fine texture is retained while the output stays under the selected 100KB ceiling.

Ready-made limits
Pick the size your form asks for
Each landing page opens the same compressor with the target already selected. A custom KB value is always available.
Why this limit matters
A practical limit for compact photos
A 50KB ceiling often needs both compression and a sensible pixel size. The engine searches for the best quality that fits before it changes dimensions.
If your form also specifies dimensions, enter those limits in Advanced settings before you compress.
Where this target helps
Profile photos for strict online forms
Small identity photos and document thumbnails
Lightweight avatars, email images, and web previews
Format support
Seven inputs. Six honest outputs.
The output picker includes JPEG, PNG, WebP, AVIF, GIF, and BMP. HEIC and HEIF remain input-only because mainstream browsers do not provide a reliable local HEIC export encoder.
| Format | Input | Output | Best use |
|---|---|---|---|
| JPEG | Yes | Yes | Best default for photographs and broad form compatibility. |
| PNG | Yes | Yes | Lossless output with full transparency. |
| WebP | Yes | Yes | Compact modern output with transparency. |
| AVIF | Yes | Yes | High-efficiency browser output powered by a local codec. |
| GIF | Yes | Yes | Static output; animated input uses the first decoded frame. |
| BMP | Yes | Yes | Uncompressed legacy output; dimensions may shrink to hit a limit. |
| HEIC / HEIF | Yes | Input only | Decoded locally, then exported to one of the six reliable formats. |
Compression method
Highest useful quality, without guessing
Search quality first
JPEG, WebP, AVIF, and GIF outputs search for the highest setting that stays below 50KB.
Resize only when required
If encoding alone cannot reach the limit, the engine reduces dimensions and searches again. It never upscales.
Report the measured result
Every file shows its actual bytes, dimensions, savings, and whether the maximum was reached.
FAQ
Questions before you compress
Does the result stay below 50KB?
The engine measures the actual output bytes and only marks a result successful when it is at or below 50KB.
Why did the image dimensions change?
If the lowest useful quality is still too large, reducing dimensions is the only reliable way to stay under a strict 50KB limit.
Are GPS and camera details removed?
Yes. Results are re-encoded in your browser, which removes EXIF metadata such as camera and GPS information.
Private by design
Your images stay yours.
The compressor has no image upload API. Analytics never receives file names or image contents.
