To compress an image to 2 KB (2,048 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 2 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 2 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 2 KB.
| Property | Original | Compressed |
|---|---|---|
| File size | 30 KB | 2 KB |
| Quality | 100% | 40-55% |
| Size reduction | — | ~93% |
| Format | JPEG / PNG | JPEG / WebP |
At 2 KB, keep dimensions at 32×32 px or below and use indexed-color PNG for crisp flat-color icons.
Two-tone or monochrome glyphs compress dramatically — a 32×32 menu icon often lands near 1 KB before you even touch the quality slider.
Remove the alpha channel if you do not need transparency — it can shave 20-30% off an already tiny PNG.
For multi-size favicons, generate separate 16×16 and 32×32 PNGs rather than one .ico to keep each request under 2 KB.

Use Compress to reduce your images to 2 KB or below, or Convert to WebP for even smaller files at the same quality.
Flat-color icons and small favicons up to 32×32 px look perfectly crisp at 2 KB. Simple two-color logos work too. Photographic content does not — reserve 2 KB for UI graphics with limited colors.
2 KB suits 16-32 px flat icons. 3 KB allows a slightly richer favicon or small avatar. 5 KB opens up tiny photographic thumbnails. The jump from 2 to 5 KB roughly doubles the dimensions you can keep sharp.
Indexed PNG (palette mode, 8-32 colors) is ideal for flat icons at 2 KB. Inline SVG is even smaller for geometric shapes and stays sharp at every resolution. Avoid JPEG at this size.
Export at 32×32 px as PNG with 32 or fewer colors — this is usually already under 2 KB. If not, open it in SammaPix Compress and reduce the palette further; flat icons tolerate aggressive color reduction with no visible loss.
Compress to 1 KB
For 1×1 transparent tracking pixels, single-color sprite tiles, ultra-minimal favicons, and CSS background micro-textures that must add virtually nothing to page weight.
Compress to 3 KB
Designed for micro-thumbnails, favicons at 16×16 or 32×32 px, email open-tracking pixels, and minimal decorative web elements that must weigh virtually nothing.
Compress to 8 KB
Ideal for web icons, small avatars on forums and chat apps, placeholder images for lazy loading, and any asset served to users on extremely slow mobile connections.
