Enter a target width or height (in pixels) and the tool scales the image, keeping the aspect ratio by default so nothing looks stretched. Prefer a relative change? Use the percentage box — 50% halves both sides, 200% doubles them.
Typical uses
- Shrink before upload — many forms and platforms cap dimensions (e.g. 1200 px wide, 2 MB).
- Fit a design slot — get exactly 1080×1080 for a square post or 1200×630 for a social preview.
- Batch shrink a folder of phone photos before archiving or emailing them.
- Prepare responsive assets at 1x/2x sizes.
How to use
1. Drop one or several images.
2. Type a width and/or height, or set a percentage. Keep "keep aspect ratio" ticked unless you really want to distort.
3. Watch each result's new dimensions and file size, then download.
Notes
- Enlarging cannot invent detail — upscaled images look soft. This is a resampler, not an AI upscaler.
- Output keeps the input format (PNG stays PNG, JPG stays JPG, WebP stays WebP) at quality 0.92.
- Everything runs locally; files never leave your device. Max 30 MB per file.
FAQ
Will resizing reduce quality?
Making an image smaller is safe and usually looks identical. Enlarging always softens the image because no new detail exists.
Can I resize many photos at once?
Yes. All dropped files use the same target size and are processed one by one.
Does it keep transparency?
Yes for PNG and WebP. JPG input had no transparency to begin with.
