Width (px)

Height (px)

Lock aspect ratio

With the ratio locked, filling in one side computes the other from each image's own proportions. Unlock it to force an exact size (which can stretch the image).

Scale (%)

Each image scales relative to its own size — the best choice when your images aren't all the same dimensions.

Preset

expand_more

Fit inside without distorting

Fitting keeps each image's proportions and stays within the preset. Turn it off to force the exact preset size instead.

Export Settings

Target File Size (Optional)

expand_more

Caps the output size. Works for JPG, WEBP, and PNG outputs.

How resizing images works here

Three steps, no software to install.

upload_file

Upload your images

Add as many as you like at once — each one is read in your browser first, so its exact dimensions show up immediately.

photo_size_select_large

Choose a size

Set exact pixels, a percentage, or a social-media preset. Every card shows its own before → after dimensions live, before anything uploads.

download

Export and download

Get your resized images back — optionally under a target file size, or converted to a different format in the same pass.

Frequently asked questions

Everything worth knowing before you resize an image here.

help

Can I resize several images at once?

chevron_right

Yes. Percentage mode is usually the best fit for a mixed batch, since every image scales relative to its own size — each card shows its own resulting dimensions before you export. Downloads come back bundled in one zip.

help

Will resizing stretch or distort my image?

chevron_right

Not unless you ask it to. With "Lock aspect ratio" on (the default), filling in one side computes the other from the image's own proportions. Unlocking it lets you force an exact width and height, which can distort — and the card badges show you that result before you export, not after.

help

What does Target File Size do?

chevron_right

It caps the output size by searching for the best encoder setting that still fits your budget — quality for JPG and WEBP, palette size for PNG. If an image is already smaller than the target, nothing is degraded to reach it. GIF and BMP have no useful equivalent, so the setting is simply ignored for those outputs.

help

What happens to transparency if I save as JPG?

chevron_right

JPG has no transparency at all, so transparent areas are flattened onto a white background rather than turning black (which is what a naive conversion produces). Choose PNG or WEBP as the output format if you need transparency preserved.

help

Does enlarging an image add detail?

chevron_right

No — scaling up past 100% interpolates pixels that were never captured, so it gets bigger, not sharper. For a better upscale, the dedicated Image Enlarger uses a sharper resampling filter.

help

What's the largest image I can resize?

chevron_right

Images up to 1 GB each are supported, at up to 10000 × 10000 pixels.

Handled with real security practices

A few specifics, not boilerplate claims.

verified_user

Real format verification

We check the actual bytes of every upload — not just its name — before touching it.

delete_sweep

No file retention

Your images are processed only long enough to build your download, then deleted immediately.

block

Abuse protection

Every upload is size-checked, and abusive IP addresses can be blocked instantly.
