Will resizing my image reduce its visual quality?

PicoFix uses high-quality bicubic canvas interpolation with image smoothing enabled. When downscaling or adjusting dimensions, sharp edges and clear text are preserved without pixelation.

What is the difference between 'Fit Within' and 'Crop to Fill'?

'Fit Within' scales your image so the entire picture fits inside your target dimensions without cropping anything. 'Crop to Fill' fills the exact width and height by centering the photo and trimming excess edges.

Are my photos uploaded to any external server?

No. All image resizing executes 100% locally inside your web browser using HTML5 Canvas. Your files never leave your device.

What image formats are supported for resizing?

PicoFix supports JPG, JPEG, PNG, WebP, AVIF, and Apple HEIC/HEIF photos. You can also convert between formats while resizing.
