Frequently Asked Questions
Common queries regarding image cropping, compression formats, and privacy:
Does cropping images here reduce image quality?
No. FileFryer extracts the exact raw source pixels based on the natural resolution of your image. If you choose PNG export, the process is 100% lossless. When exporting to WebP or JPEG, you have full granular control over the quality slider.
Are my photos uploaded to any server?
No, absolutely not. All cropping, aspect ratio scaling, rotating, and format encoding happens 100% locally inside your web browser sandbox using client-side HTML5 Canvas. Not a single pixel ever leaves your device.
Is there a file size or dimension limit?
Because processing happens locally through your device's hardware, limits depend only on your system memory and browser canvas capabilities. High-resolution photos from 24MP–48MP cameras and smartphones are supported with ease.
Which format should I choose: WebP, PNG, or JPEG?
Use WebP for modern web applications to get the smallest file sizes with superior visual clarity. Use PNG when you need transparent backgrounds or circular avatar masks. Use JPEG for broad compatibility across legacy photo printing and office suites.
Can I crop images into round circles for profile avatars?
Yes! Select the Avatar / Profile preset in the Social category or set the shape to round. When exported in PNG or WebP, the tool clips the outside border into a clean transparent circle mask.
Can I specify exact pixel dimensions for my crop?
Yes. You can enter exact custom pixel width and height in the dimension inputs, toggle the aspect ratio lock to preserve proportions, and fine-tune your crop area without manual approximation.
