Frequently Asked Questions
Common questions about client-side resizing, interactive stretching, and format compression:
How do the interactive stretch handles work?
The canvas provides 4 corner anchors and 4 edge pills. Grabbing any handle scales the image in that direction with an immediate live stretch preview, updating pixel dimensions and percentage stats in real time.
Can I stretch an image without locking the aspect ratio?
Yes. Toggle off Aspect Ratio Lock to stretch width or height independently without constraint. To scale proportionally without distortion, keep Aspect Ratio Lock turned ON.
Does resizing reduce image sharpness or quality?
FileFryer employs bicubic canvas interpolation to preserve crisp lines, fine text, and accurate color gradients. When exporting to PNG, output quality is 100% lossless.
What is the difference between image resizing and cropping?
Cropping clips away outer areas of an image to change composition, while resizing scales and stretches the entire image to match new target pixel dimensions.
Are my uploaded photos safe and private?
Yes, 100%. All processing runs locally inside your browser session using HTML5 Canvas. No data is sent over the network, stored on servers, or tracked.
Can I resize transparent PNGs and WebP graphics?
Yes. Selecting PNG or WebP maintains full alpha channel transparency, ensuring clear backgrounds for logos, watermarks, icons, and UI assets.
