About this tool
Resizing reduces both dimensions and file size, which is often more effective than compression alone. Enter a target width or height and the other dimension is calculated automatically to preserve the aspect ratio; unlock the ratio only when you genuinely need a non-proportional size. High-quality browser scaling is used, and the output format matches your input so no unexpected conversion happens.
Frequently asked questions
- Will resizing distort my photo?
- Not with the aspect ratio locked, which is the default. Entering one dimension calculates the other proportionally. Unlocking the ratio lets you set both freely, which can stretch the image.
- Can I make an image larger?
- Yes, but enlarging cannot add real detail — the result will be somewhat soft. Upscaling works best for modest increases.
- Does resizing change the format or quality?
- The output keeps your input format. JPG and WebP are re-encoded at high quality; PNG stays lossless.
