01 / WHAT

What is a bulk image resizer?

One size setting, many images

Choose a target width or a percentage and apply it to up to 30 images in one batch. Each file is processed in your browser.

Proportional images, ready to download

The height follows each image’s original aspect ratio. Export as JPG, PNG or WebP, then download individually or together as a ZIP.

Resizing changes dimensions

This tool changes pixel dimensions. Ordinary enlargement does not recreate detail; use compression when your main requirement is a smaller file size.

LIFESTYLE IMAGES, RESIZEDActual tool outputs

One batch, one target width: 600 px. Every before/after pair uses the same display scale so the size change stays visible.

02 / WHERE

Where can you use resized images?

Product galleries

Prepare product images with a consistent width for your shop. Mixed aspect ratios will still have different heights.

Articles and newsletters

Fit illustrations to the content width of your publishing workflow before adding them to an article or email.

Presentations and shared folders

Create smaller working copies for slides or handoffs while keeping your original images separate.

03 / WHY

Why resize your photos in bulk?

Set the width once

Avoid entering the same dimensions for every file. Review the output dimensions in the results list before downloading.

Keep the proportions intact

Automatic height calculation helps avoid stretched subjects when applying one width to landscape and portrait images.

Keep source files on your device

Free resizing does not require an account or upload your images. Downloads are new files, leaving the originals untouched.

04 / WHEN

When should you resize an image?

Your originals are larger than needed

Reduce large camera exports when your destination only needs a smaller pixel width.

A batch has inconsistent widths

Apply a common width before a handoff. Enable standard enlargement only if smaller inputs also need to reach that width.

You need a percentage-sized copy

Choose percentage mode when you want each source reduced proportionally rather than forcing every image to the same width.

GOOD TO KNOW

Frequently asked questions

Is batch image resizing free?

Yes. The free resizer works without logging in. Each batch supports up to 30 images, with a 20 MB limit per file.

Can I set both width and height?

This tool sets width or percentage and preserves the original proportions. Use the crop tool first if you need a particular aspect ratio.

Why did a small image stay the same size?

Enlargement is off by default. Enable “Allow standard enlargement” to increase its dimensions. This is ordinary resizing, not AI enhancement.

Will my photo metadata be preserved?

No. Exporting creates a new encoded image without the original EXIF metadata. JPG output also fills transparent areas with white.

What if an image cannot be processed?

Check the file type and size. Inputs support JPG, PNG and WebP up to 32 megapixels. Outputs also have a 16,384 px per-side limit, and device memory may impose lower limits.
