Compress Image to 50KB (Quick Guide)
This tool targets ~50 KB by tuning JPEG quality entirely in your browser. No uploads—privacy by design.
1) Core idea
Target size = 50 × 1024 bytes. We perform a binary search over JPEG quality so the final blob size lands close to 50 KB.
2) Flow
- Upload or drag & drop your photo.
- Auto‑compress finds a quality level near 50 KB.
- Optionally fine‑tune with the quality slider preview.
- Download the JPEG output.
3) Sanity checks
- Very high‑detail or very large images may exceed 50 KB—resize first if needed.
- Metadata (EXIF) is removed on export which slightly reduces size.
- PNG/WebP uploads are converted to JPEG here; transparency is flattened.
4) Shortcuts
- Crop or resize before compressing to reach 50 KB more reliably.
- Use plain backgrounds and fewer gradients to reduce size.
- For logos needing transparency, use a PNG‑specific tool instead.
5) Pitfalls
- At low qualities, text/lines can appear blocky—prefer resizing over extreme compression.
- Repeated recompression of JPEGs compounds artifacts—work from the original when possible.
6) Micro examples
- Profile photo 800×800 → typically 35–55 KB at medium quality.
- Retina screenshots → often need resizing to reach 50 KB.
7) Mini FAQ
- How precise? Usually within ~35–55 KB given encoder steps.
- Is it safe? Everything runs locally in your browser.
- Output type? JPEG.
8) Action tip
If the file refuses to hit 50 KB, resize the longest side to ~1200–1600 px, then compress again.
