Resizing photos one at a time is slow when you have a whole folder. This tool resizes a batch of images together — by percentage or to a fixed width — and lets you download them all at once.

Every image is processed in your browser, so nothing is uploaded.
How to use Bulk Image Resizer
Using Bulk Image Resizer takes only a few seconds and just four simple steps — no sign-up, no software, and nothing to learn:
- Choose how to resize: Pick a percentage scale or a fixed target width.
- Add your images: Drop in as many photos as you like.
- They're all resized: Each image is resized the same way, keeping its aspect ratio.
- Download: Save them individually or all at once.
What you can do with Bulk Image Resizer
Bulk Image Resizer is built to do one job well, and gives you everything you need to get it exactly right:
Batch processing. Resize a whole set of images in one go.
Percent or width. Scale by a percentage or set an exact width.
Aspect kept. Heights adjust automatically so nothing is distorted.
Private and free. All resizing happens in your browser, no watermark.
A folder of photos, resized fast
Preparing images for a website, an email, or an upload often means resizing many at once. Doing it in a single batch saves time, and because it runs locally, even private photos never leave your device.
Whether you need it once or every day, Bulk Image Resizer keeps the process quick and predictable. Because it focuses on a single task, there are no crowded menus to wade through — you open the page, set what you need, and get your result. That simplicity is exactly why a dedicated image tool beats a heavyweight editor for a job like this.
Everything runs in your browser
Unlike most online tools, Bulk Image Resizer never uploads your image to a server. The moment you choose a file, it is processed right here in your web browser using your own device's power. Nothing is sent over the internet, nothing is stored, and nothing is shared with anyone.
That gives you two real advantages. First, it is private: sensitive documents, ID photos and personal files never leave your computer or phone. Second, it is fast — there is no slow upload or download round-trip, so even large files are handled almost instantly. And it is completely free, with no watermark added to your result and no account required.
Tips for the best results
- Start from the highest-quality original you have — the better the input, the better the result from Bulk Image Resizer.
- Check the exact requirement — size, dimensions, or format — before you begin, so you only need to do it once.
- Batch processing: Resize a whole set of images in one go.
- Percent or width: Scale by a percentage or set an exact width.
- Everything is repeatable — if the result isn't quite right, just adjust the settings and run it again. Nothing is uploaded, so you can try as many times as you like.
