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.
