Multiple files supported

Resize dozens of images in one pass

Instead of opening each photo individually, this tool lets you select a whole folder's worth of images, set one target width and quality, and get every resized image back in a single ZIP download — all processed locally in your browser.

How it works

Select multiple images — JPEG, PNG or WebP all work.

Set a target width in pixels; height scales automatically to preserve aspect ratio.

Choose a quality level between 0.1 (smallest file) and 1 (best quality).

Click resize and a ZIP file downloads with every image processed.

Good for

Preparing a batch of product photos for a website, shrinking phone camera photos before emailing them, or standardizing image sizes across a folder before uploading them somewhere with strict size limits.

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

There's no hard cap, but very large batches depend on your device's available memory since processing happens entirely in your browser tab.

What format will the resized images be in?

Resized images are saved as JPEG inside the ZIP. If you need a different output format, use the Image Format Converter's batch mode instead.

Will resizing crop or distort my photos?

No — only the width you set is applied directly; height is scaled proportionally so the original aspect ratio is preserved and nothing is cropped or stretched.

Can I resize images to be larger than the original?

Yes, but enlarging a photo beyond its original resolution will make it appear softer or blurrier, since no new detail is created — the tool works best for shrinking images down.

Using this in a Central Government office

Bulk resizing earns its keep when you have a folder of scans rather than a single file — a set of documents captured page by page, photographs from an inspection or a site visit, or a batch of certificates that all have to clear the same upload ceiling.

Where this comes up

A folder of scanned pages that each need to fit under a portal's per-file limit.

Inspection or site-visit photographs going into a report, where full-resolution images make the document unusable.

Batch preparation of certificates or supporting documents for a claim submission.

Resize by dimension, not just by quality

Reducing JPEG quality alone degrades the image while leaving the pixel dimensions unchanged. Reducing the dimensions is usually the better lever: a scan at 3000 pixels wide reduced to 1600 remains completely legible on screen and in print at document size, and the file becomes a fraction of the size. Only drop quality after the dimensions are sensible.

Keep the originals

Resizing is not reversible. Work on copies and keep the originals wherever the images are evidence — inspection photographs, damage records, anything that might be examined later. Once a photograph has been downsized, detail that was in the original is gone for good.
