Frequently asked questions

How do I resize an image without losing quality?

Upload your image, enter the desired width and height, and keep the aspect ratio checkbox enabled. Our tool uses canvas-based resizing which preserves as much detail as possible at the new dimensions.

Can I resize multiple images at once?

Currently our tool processes one image at a time. Upload your image, resize it, download it, then upload the next one.

What is the maximum image size I can resize?

We recommend images up to 25MB. Very large images may take a moment to process depending on your device.

Will resizing change my image format?

No. The output format matches your input — JPG stays JPG, PNG stays PNG.

Can I resize an image to make it larger?

Yes, you can increase dimensions. Keep in mind that enlarging an image beyond its original size may reduce sharpness since pixels must be interpolated.
