To compress an image to 25 KB (25,600 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 25 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 25 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 25 KB.
| Property | Original | Compressed |
|---|---|---|
| File size | 375 KB | 25 KB |
| Quality | 100% | 40-55% |
| Size reduction | — | ~93% |
| Format | JPEG / PNG | JPEG / WebP |
Many visa portals require exactly 25 KB — set quality to 40-60% and verify the output size before uploading.
Resize to 500×500 px first, then compress — this combination consistently hits the 25 KB target.
If JPEG compression is not enough, convert to WebP and then back to JPEG at lower quality for a smaller file.
Remove EXIF metadata (GPS, camera info) to shave an extra 2-5 KB off the file size.

Use SammaPix Compress with the quality slider set to around 40-55%. If the result is still over 25 KB, resize the image to 500×500 px first, then compress again. Most visa portals accept JPEG format.
Yes, especially for small-dimension photos (400-600 px). At 25 KB a face photo looks sharp enough for identification. The key is to resize the dimensions down before compressing, rather than compressing a huge image.
For passport or visa photos, 350×450 px at 25 KB produces a clear result. For general use, keep the longest side under 600 px. Larger dimensions at 25 KB will appear visibly blurry.
Yes. EXIF metadata (camera model, GPS coordinates, timestamps) can add 5-15 KB to a JPEG file. Use the SammaPix EXIF Remover tool first, then compress — you may reach 25 KB at a higher quality setting.
