To compress an image to 30 KB (30,720 bytes) for free, drop it into SammaPix Compress and adjust the quality slider until the output meets the target — for most photos, quality 30-55% reaches 30 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 30 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 30 KB.
| Property | Original | Compressed |
|---|---|---|
| File size | 450 KB | 30 KB |
| Quality | 100% | 70-85% |
| Size reduction | — | ~93% |
| Format | JPEG / PNG | JPEG / WebP |
At 30 KB you can maintain a 400×400 px profile photo at quality 65-75% — sharp enough for social media and team pages.
Crop to a 1:1 square before compressing — most platforms display profile pictures as circles or squares, and cropping first maximizes the useful pixels.
For directory headshots, export at 350×350 px and 70% quality — this reliably hits 30 KB with a professional look.
Use WebP format to get roughly 25% better detail at 30 KB compared to the same file in JPEG — especially noticeable in facial details like eyes and hair.

Yes. Most social platforms display profile photos at 150-400 px. A 30 KB image at 350×350 px looks clean and professional. Platforms like Twitter, LinkedIn, and Slack all display profile pictures at this range.
Crop tightly around the face and shoulders, resize to 300-400 px wide, then compress at 65-75% quality in SammaPix. This workflow consistently produces 25-32 KB files that look sharp in directory grids.
Use 30 KB when page speed is critical (directories with dozens of headshots, mobile-first sites) or when a strict upload limit exists. Use 50 KB when slightly more detail matters, like individual staff bio pages.
For square profile photos: 300-400 px. For rectangular thumbnails: 400×300 px or 350×250 px. Going above 500 px wide at 30 KB will introduce visible blurriness in photographic content.
