Resize many photos in one pass

Resizing a whole batch of photos at once

Resizing one photo at a time is fine occasionally, but it doesn't scale when you're preparing a folder of product shots, a gallery for a website, or a batch of images for an email campaign. This tool processes every file you upload against the same settings in one pass, then bundles all the resized files into a single zip so you get one download instead of dozens.

Exact dimensions vs percentage scale

Use exact dimensions when a platform has a strict requirement — a maximum width for a CMS, a fixed size for thumbnails. With "keep aspect ratio" checked, each photo is scaled to fit inside your target width and height without stretching or distorting it, so portrait and landscape photos in the same batch both come out looking correct. Percentage scale is simpler when you just want everything smaller by the same proportion, regardless of each photo's original size.

Choosing an output format

JPEG is the smallest option for ordinary photos and is supported everywhere. PNG keeps transparency and sharp edges, at a larger file size — useful for graphics and screenshots rather than photos. WebP typically produces the smallest files of the three at a comparable quality level, and is well supported by modern browsers and platforms.

Frequently asked questions

Is there a limit on how many photos I can resize at once?

There's no hard limit built into the tool, but very large batches take longer and use more of your device's memory since everything processes locally rather than on a server.

Does resizing reduce quality?

Making an image smaller doesn't meaningfully hurt quality. Making it larger than its original size will look softer, since new pixels are being estimated rather than captured.

Are my photos uploaded anywhere?

No. Every resize happens locally in your browser, and the zip file is assembled on your device before download.
