Frequently asked questions

Completely safe. Every edit happens entirely within your browser — your images never leave your device. We have no access to your files and nothing is uploaded, stored, or transmitted anywhere. You could even use the editor offline once the page has loaded.

No. All processing is done locally using your browser's Canvas API. There are no servers involved. This makes it safe for private photos, sensitive documents, or anything you wouldn't want leaving your device.

We use only anonymous analytics to understand how the site is used — no personal data, no file contents, no tracking across other sites. We don't sell data. See our Privacy Policy for full details.

Upload your image, select the Resize tab, then enter your target dimensions in pixels or choose a percentage. Use the lock icon to maintain the aspect ratio. You can also tap the quick resize buttons (0.25x, 0.5x, 1x, 2x, 4x) for instant scaling. Hit "Apply resize" to confirm.

Upload your image and select the Crop tab. A crop overlay will appear on your image with draggable handles at the corners and edges. Drag the handles to set your crop area, or type values directly into the Top/Bottom/Left/Right fields. When happy, tap "Apply crop" to confirm.

Cropping is lossless — it simply removes the edges without touching the remaining pixels. Resizing inherently changes the pixel count, so some quality change is unavoidable, but we use high-quality bicubic resampling to keep it as sharp as possible. Exporting as PNG is always lossless. JPG and WEBP use a quality slider — the default is 92%, which is excellent quality.

You can upload JPG, PNG, WEBP and GIF images up to 25 MB each. You can export as PNG (lossless), JPG, or WEBP with an adjustable quality slider.
