Batch Tools · Bulk Rename & Resize

Bulk rename and resize many images at once

Drop in a whole folder's worth of photos, set one target size and a naming pattern, and download every file resized and renamed in a single ZIP.

Drop many images here, or click to choose files
Every file gets the same size and naming pattern
🔒 Every file is resized, renamed and zipped locally in your browser — nothing is uploaded to a server.

How it works

01

Add your batch of photos

Drop in dozens of images at once — event photos, product shots, scanned documents.

02

Set one size and naming pattern

Choose a target width/height and a filename prefix; every file follows the same rule.

03

Download one ZIP

All resized, renamed files come back in a single ZIP, ready to upload or archive.

Processing many images at once, locally

Resizing and renaming a folder of photos one at a time is slow, and most single-image tools aren't built for batches. This tool processes every file you drop in in one pass, applying the same width/height and a consistent, sequential naming pattern to each, then packages the results into a single ZIP — all without uploading the batch anywhere.

Keeping this work in the browser also means there's no per-file upload limit or queue to wait through — the practical limit is simply how much your device can process at once, which for typical photo batches is fast.

Common uses: preparing a folder of product photos for an online store listing, standardising a batch of event photos before sharing them, or cleaning up inconsistent filenames from a camera or phone export. For a single image that needs a precise crop rather than a batch resize, use Resize & Crop, or Compress Image if file size, not dimensions, is the main issue.

Frequently asked

What happens if I only set a width, not a height?

With 'Keep aspect ratio' checked, the height is calculated automatically from each image's own proportions.

How are files named?

Using your prefix followed by a zero-padded sequence number, e.g. photo-001.jpg, photo-002.jpg, continuing from your chosen start number.

Is there a limit to how many files I can process?

No fixed limit, but very large batches take longer since resizing and zipping both happen in your browser.
