Compress Image to 100KB (Quick Guide)
Hit ~100 KB by adjusting JPEG quality locally in your browser. Fast, private, and no uploads.
1) Core idea
Target size = 100 × 1024 bytes. We binary‑search JPEG quality until the encoded result is near 100 KB.
2) Flow
- Upload your image (JPG/PNG/WebP/GIF, etc.).
- Auto‑compress finds a suitable quality for ~100 KB.
- Optionally use the slider preview to fine‑tune quality vs size.
- Download the JPEG result.
3) Sanity checks
- Large, detailed images might sit above 100 KB at acceptable quality—resize if needed.
- Metadata (EXIF) is removed; colors and pixel data remain.
- Non‑JPEG inputs are converted to JPEG; transparency is flattened.
4) Shortcuts
- Resize longest side to ~1600–2200 px to reach 100 KB easily.
- Prefer clean backgrounds; avoid heavy noise/grain for better compression.
5) Pitfalls
- Over‑compressing portraits can introduce banding and blockiness—balance with modest resizing.
- Re‑compressing already‑compressed JPEGs adds artifacts—use originals when possible.
6) Micro examples
- Social banner 1920×1080 → often 70–110 KB at medium quality.
- Phone camera shot 4032×3024 → resize first, then compress to ~100 KB.
7) Mini FAQ
- Precision? Typically within ~80–110 KB.
- Safe? Yes—the process happens locally.
- Output? JPEG only.
8) Action tip
If quality looks too low near 100 KB, resize modestly (e.g., 75–85% width) and re‑compress.
