Resize Image

Resize images precisely

Enter a target width or height in pixels and the tool rescales the image. The aspect ratio is locked 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 (for example 1200 px wide, 2 MB).
• Hit an exact size — 1080×1080 for a square post, 1200×630 for a social preview, 1920×1080 for a slide.
• Batch-shrink a folder of phone photos before archiving or emailing.
• Prepare responsive assets at 1x and 2x for a website.

How to use

• Drop one or several images.
• Type a width and/or height, or set a percentage. Keep "keep aspect ratio" ticked unless you deliberately want to distort.
• Check each result's new dimensions and file size, then download.
• When both width and height are set with the lock on, the smaller ratio wins so the image fits inside the box.

Quality and limits

• Enlarging cannot invent detail — upscaled photos 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 in your browser; files never leave your device. Up to 30 MB per file.

Frequently asked questions

• Will resizing reduce quality? Downscaling looks clean; upscaling always softens.
• Can I resize many images at once? Yes.
• Does it keep transparency? Yes, PNG and WebP transparency is preserved.
• Is it free? Yes, no sign-up required.

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.
