To compress an image to 5 KB (5,120 bytes) for free, drop it into SammaPix Compress and adjust the quality slider until the output meets the target — for most photos, quality 10-30% reaches 5 KB. Processing happens 100% in your browser using the Canvas API — no upload, no signup, no watermark. Tested on 100 real images: SammaPix matched SSIMULACRA 2 quality scores above 65 (no visible loss) at all output sizes >= 50 KB. For sizes below 25 KB, expect visible compression artifacts on photographic content — vector-style images and screenshots fare best.
Open the SammaPix Compress tool and drag your image into the drop zone. Supports JPEG, PNG, WebP, and GIF.
Adjust the quality slider until the output size is at or below 5 KB. Lower quality = smaller file.
Download your compressed image instantly. Everything runs in your browser — your photos never leave your device.
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.
