Compress JPG to 20KB (Quick Guide)
This tool targets ~20 KB by tuning JPEG quality in your browser. Nothing is uploaded.
1) Core idea
Goal size = 20 × 1024 bytes. A binary search adjusts JPEG quality so the encoded file lands near 20 KB.
2) Flow
- Upload your JPG.
- Auto‑compress searches for a quality near 20 KB.
- Preview, then download the compressed JPG.
3) Sanity checks
- Very detailed or very large images might not reach 20 KB—resize first.
- EXIF data is removed during export (smaller size, more private).
4) Shortcuts
- Crop/resize to ~600–900 px longest side before compressing.
- Use plain backgrounds for better compression.
5) Pitfalls
- Text/screen content can look blocky at very low quality—prefer resizing.
- Avoid re‑compressing an already compressed JPG; use the original when possible.
6) Micro examples
- Passport headshot 600×600 → typically 14–20 KB at medium quality.
- Phone landscape 4032×3024 → needs resizing to reach 20 KB.
7) Mini FAQ
- Precision? Usually ~14–20 KB.
- Safe? 100% local processing.
- Output? JPG.
8) Action tip
Resize longest side to ~800–1200 px if auto‑compress can’t reach 20 KB, then retry.
