Frequently Asked Questions
How do I resize an image online?
Upload your image, enter the target width and height in pixels, and click Resize. With the aspect-ratio lock on, typing one dimension fills in the other automatically so the picture never looks stretched. You can also use the 25% / 50% / 75% quick-scale buttons.
Will resizing distort or stretch my image?
Not if you keep the aspect-ratio lock enabled — width and height stay proportional. Unlock it only when you deliberately want to force exact dimensions, which can stretch the picture.
Can I change the file format while resizing?
Yes. Keep the original format or convert to JPG, PNG, or WebP in the same step. For JPG and WebP you can also set the quality to balance sharpness against file size.
What image formats can I upload?
JPG, PNG, WebP, GIF, BMP, TIFF, and AVIF. Output is delivered as JPG, PNG, or WebP. Photos are auto-rotated using their EXIF orientation so they stay upright.
Can I upscale a small image to a larger size?
Yes — enter dimensions larger than the original and we will scale it up. Note that enlarging cannot add detail that was not in the original, so very large upscales look softer.
Is there a maximum size?
Output is capped at 10000×10000 pixels. Uploads can be up to 20 MB on the free plan and 50 MB on Pro.
Is it safe and free?
Yes. Images are processed over an encrypted connection and deleted within 1 hour — we never store or share them. Resizing is free, with a daily watermark-free allowance; beyond it, output stays free but carries a small PaperFlow mark. Upgrade to Pro for unlimited clean output.
