To compress an image to 10 KB (10,240 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 10 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 10 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 10 KB.
| Property | Original | Compressed |
|---|---|---|
| File size | 150 KB | 10 KB |
| Quality | 100% | 40-55% |
| Size reduction | — | ~93% |
| Format | JPEG / PNG | JPEG / WebP |
Resize to 200-400 px on the longest side before compressing — this is the sweet spot for 10 KB quality.
Convert to WebP format first — a 10 KB WebP looks as good as a 25 KB JPEG.
For product thumbnails, crop tightly around the product to eliminate background pixels.
Use progressive JPEG encoding if the target system doesn't support WebP — it renders faster at small sizes.

Upload your image to SammaPix Compress and lower the quality slider until the output shows 10 KB or less. If the image is too large, resize it to under 400 px first using our Resize tool, then compress again.
Yes, absolutely. At 200-300 px wide, a 10 KB image looks sharp on screens. Most e-commerce product grids, blog post thumbnails, and directory listings use images around this size for fast page loads.
Technically yes, but it will be very blurry at full resolution. For best results, resize to 200-400 px first, then compress. This gives you a sharp, lightweight image instead of a blurry full-size one.
At 200 px wide, barely noticeable. At 400 px wide, 20 KB will look slightly sharper in detailed areas (hair, text, edges). If your use case allows 20 KB, go with that for better quality.
