Typical results when compressing a photo to 5 KB.
| Property | Original | Compressed |
|---|---|---|
| File size | 75 KB | 5 KB |
| Quality | 100% | 40-55% |
| Size reduction | — | ~93% |
| Format | JPEG / PNG | JPEG / WebP |
At 5 KB, resize your image to 100×100 px or smaller first — large images cannot reach 5 KB at usable quality.
Use WebP format — it delivers 2-3x better quality than JPEG at the same file size.
Remove all metadata (EXIF data) to save extra bytes — use our EXIF Remover tool first.
For logos and icons, convert to PNG with limited colors (palette mode) before compressing.

Use Compress to reduce your images to 5 KB or below, or Convert to WebP for even smaller files at the same quality.
First resize your image to a very small dimension (under 150×150 px) using our Resize tool. Then open the Compress tool, set quality to 20-40%, and download. For icons and logos, PNG with reduced colors often works better than JPEG.
5 KB images are ideal for favicons (16×16 to 48×48 px), email signature logos, tiny social media avatars, placeholder thumbnails, and ultra-lightweight web page decorations that need to load instantly.
At very small display sizes (under 150×150 px), yes. A favicon at 32×32 px looks crisp at 5 KB. But a full-size photo compressed to 5 KB will be extremely blurry — this size is meant for tiny graphics only.
For photos: WebP delivers the best quality-to-size ratio. For logos/icons with flat colors: PNG with palette mode. For compatibility with old systems: JPEG at very low quality.
