About Resize & Transform

Changing how many pixels an image has is the other half of making it fit a form, a slide, or a social box. Resize by pixels, percentage, or a preset. Crop when composition is the problem, not size. Rotate and flip are for the phone picture that landed on its side.

Resizing down is cheap and usually what you want. Resizing up doesn't recover detail; it invents pixels. I won't pretend a 200-pixel logo becomes a poster because a slider went to the right.

Batch resize applies one target size to many files and zips the result. Use it for a set of product shots that all need to be 1200 pixels on the long edge.

Tools in this category

Resize

Resize scales by width and height, by percentage, or with social-style presets. You can lock aspect ratio so the picture doesn't stretch. This is the default tool when someone says “make it smaller” and they mean dimensions, not JPEG quality.

Crop

Crop cuts to a rectangle, freeform or a ratio preset (1:1, 16:9, 4:5, and the rest). Pixels outside the box are gone. If you only needed a smaller file and the whole frame still matters, use Resize instead.

Rotate

Rotate turns the image by any angle, not only 90-degree hops. 90/180/270 keep the pixel grid clean. Arbitrary angles fill the new corners; those pixels weren't in the photo.

Flip

Flip mirrors horizontal or vertical. It is the tool for a scan that came out backwards, or a product shot that needs to face the other way, without opening an editor.

Batch resize

Batch resize takes a pile of images and writes them all to the same pixel size. Same encoder as the single resize page, zip on the way out. Mixed aspect ratios will letterbox or stretch depending on the options you pick, look at one file first if that matters.

Common questions

Should I resize before or after compressing?

Resize first. Compression encodes the pixels you actually want to keep. If you JPEG-compress a 4000-pixel photo and then scale it to 800, you paid to encode detail you immediately threw away.

Does cropping change the file format?

The result is encoded from the pixels in the crop, usually as PNG from this workbench. If you need a JPEG afterwards, run it through the JPEG compressor. Cropping itself is a geometry job, not a format job.

Can I resize a whole folder to the same dimensions?

Yes: batch resize. Drop many files, set the size once, download a zip. The single-file page is for checking the look of one image before you inflict those numbers on forty others.

Why these tools don't upload your files

There is no server to upload to. Each page is a static file, and the work happens in your browser. Your file is read from disk into memory, processed, and handed back as a download. Once the page has loaded you can disconnect from the network and it keeps working. The longer explanation
