Frequently asked questions
Is there a limit on how many images I can resize at once?
There is no account or server limit because the work happens on your device. The practical limit is your device’s memory, so on a phone it is best to work in batches of 10–20 at a time.
Will resizing to (long edge) stretch or distort my image?
Not with the default “fill / cover” mode — it scales the image proportionally and crops the edges so nothing is squashed. Switch to “fit / contain” to see the whole image with a background, or “exact” only when you deliberately want to stretch it.
Are my photos uploaded when I resize?
No. Resizing happens in your browser using the Canvas API, so your images never leave your device and the result is instant.
Can I resize several images to (long edge) at once?
Yes. Add multiple files and every one is resized to the same (long edge) settings. Download them individually or all together.
Does resizing reduce quality?
Making an image smaller is safe and usually looks sharp. Enlarging beyond the original size cannot add real detail, so results are smoothed. Keep the quality setting high (90%+) when you export.
What file format should I save as after resizing to (long edge)?
JPG is the best default for photos and the smallest, PNG preserves transparency, and WebP offers a great size-to-quality ratio for the web. Pick the format that matches where you will use the image.
