Fit, Fill, or Stretch — which mode should you use?

Fit keeps your entire image visible inside the target frame, adding a background to fill empty space. Best for passport photos and images where nothing can be cut off. Fill crops the image to perfectly fill the frame — ideal for Instagram posts or LinkedIn banners. Stretch distorts the image to exactly match the target size — only use when distortion is acceptable.

Frequently asked questions

How do I resize an image without losing quality?
Use Fit or Fill mode (not Stretch) and download as PNG for lossless output, or JPG at high quality. Resizing down rarely causes noticeable quality loss. Resizing up (upscaling) can cause some softness — this is inevitable with any tool as pixel data is being generated.
Is my image uploaded to a server?
No. Your image never leaves your device. All processing runs locally in your browser using the HTML5 Canvas API. No data is transmitted, stored, or logged.
What file formats can I download?
JPG (best for photos, smallest file size), PNG (lossless, supports transparency), and WEBP (modern format, smallest size with great quality). JPG is recommended for most social media uploads.
What is the difference between Fit and Fill?
Fit scales your image to fit inside the target frame without cropping — empty areas are filled with your chosen background colour. Fill scales your image to completely cover the frame, cropping edges as needed. Both preserve aspect ratio. Stretch forces the image to the exact target dimensions, which may distort it.
