Frequently asked questions
Can this fix a very blurry photo?
Only partly — and we would rather tell you the truth than overpromise. Sharpening strengthens edges that exist, so a soft or slightly blurry photo improves a lot. Heavy blur and motion blur remove detail completely, and no tool can restore detail that was never captured. Try the "Reduce blur" preset: if the photo has anything to work with, you will see the difference.
Is my photo uploaded to a server?
No. Every step — sharpening, colour, upscaling, saving — runs inside your own browser on your own device. Your photo is never sent anywhere, which makes this safe for personal, school and work pictures.
What does the 2× upscale actually do?
It doubles the width and height using high-quality smooth resizing, then applies your sharpening settings. The result prints and displays bigger without jagged edges, but the detail is spread thinner — upscaling makes a photo larger, not magically more detailed.
Will enhancing change or damage my original?
No. The tool works on a copy in your browser and your original file stays exactly as it was. Try as many settings as you like — if you push the Enhance slider too far, edges can start to look harsh or grainy; just slide back a little.
Which format should I save in?
JPG suits almost every photo and keeps the file reasonably small. Choose PNG if your image has transparency or crisp screenshots and text, and WebP if you want a modern format that is usually smaller than both.
