Frequently asked questions
- Will the aspect ratio be distorted?
- The aspect ratio is preserved by default. If you prefer, turn off "Lock aspect ratio" and enter any dimensions you like.
- Does upscaling reduce quality?
- Yes. Enlarging an image beyond its original size makes it blurry, whereas shrinking it usually costs no quality.
- Which format is saved?
- PNG inputs are saved as PNG and everything else as JPEG (transparency is preserved).
- Can I resize many images to the same size?
- This tool works on one image at a time. To collect many images into a PDF, Image → PDF scales them to the page automatically.
