FAQ

Increase image resolution — common questions

How do I increase image resolution for free?

Upload your image to FixTheFile and select "Upscale image". The resolution increases automatically, and your file downloads instantly.

Will increasing resolution make my image blurry or pixelated?

No — FixTheFile uses AI to add realistic detail as it increases resolution, rather than just stretching the existing pixels, which is what causes blurriness in basic resizing.

What resolution do I need for printing?

For most printing, 300 DPI at your target print size is recommended. FixTheFile's 4× boost is often enough to bring a small web image up to print quality.

Does this work for both photos and graphics?

Yes — FixTheFile works on photos, screenshots, and most graphic images, though results are generally best on photos.

Is there a limit to how large I can upscale an image?

FixTheFile currently supports up to 4× the original resolution in a single conversion.
