Bulk Image Resizer is a free online tool that resizes up to 20 images at once to fit a maximum width and height, right inside your browser. Set a target size, choose an output format, and download each resized file individually or grab the whole batch as a single ZIP.
A single photo is easy to resize by hand, but a folder of product shots, scanned pages, or exported screenshots is not -- especially when the images do not share the same shape. This tool scales every file to fit inside the size you set rather than stretching each one to identical dimensions, so a mix of portrait, landscape and square photos all come out the right size without distortion. Ticking Don't enlarge keeps small images from being blown up past their real resolution, which matters when a batch includes a few files that are already smaller than the target.
Every resize happens on a canvas inside your browser: nothing is uploaded to this site or to any external service, so private photos, scans, or unreleased product shots never leave your device. The one exception is Download All, which fetches a small, widely used library the first time you build a ZIP file -- resizing itself keeps working even without that request succeeding, and every file can still be downloaded on its own. The batch limit is 20 files per session.
Click Choose Images and select up to 20 files at once -- add more later if you have not reached the limit.
Type a Max Width and/or Max Height in pixels. Leave one blank to scale only by the other side.
Choose PNG, JPEG or WebP under Output Format, and drag the Quality slider for JPEG or WebP.
Click Resize All. Download files one at a time from their row, or click Download All (ZIP) to save every resized image together.

Up to 20 per batch. Add more with Choose Images as long as you are under that limit; if you pick files that would push you over 20, only enough to reach the limit are added and the rest are skipped.
Not necessarily, and that is by design. Each image is scaled to fit inside the max width and/or height you set while keeping its own aspect ratio, so a portrait photo and a landscape photo in the same batch come out different actual sizes even though both fit the same box. For one exact size on every file, use the single-image Image Resizer with Keep original aspect ratio turned off.
It stops an image that is already smaller than your target size from being scaled up, which would just blur it. With the box ticked (the default), a small image is left at its original size instead of being stretched larger; untick it if you specifically want every file blown up to the same box.
Yes. Once at least one file shows Done, Download All (ZIP) becomes available and saves every resized image in a single .zip file. It builds the ZIP with a small library fetched once from a CDN, so that one button needs a connection even though resizing itself does not.
Its row shows Failed instead of Done, and the rest of the batch keeps resizing normally. This usually means the file was not really a readable image or was corrupted -- open it in an image viewer to confirm, then try again.
Image Resizer resizes one image at a time to an exact width and height you type in, with presets for common social media sizes. This tool is built for batches: it fits many images at once inside a max size, keeping each one's own aspect ratio, with per-file and ZIP downloads.
