Why Use a Private, Offline, Browser-Based Image Cropper?
100% Private & Safe (Zero Server Uploads)
Unlike typical online photo editors, your photos are never transmitted over the internet or uploaded to remote servers. All processing is executed locally inside your web browser using HTML5 Canvas technology. Your sensitive images remain on your device at all times.
Instant Batch Cropping
Save time by cropping up to 100 photos in one go. Whether you are prepping products for e-commerce stores, adjusting images for photo prints, or standardizing gallery uploads, the same zoom, position, straighten, border, and background are applied to every photo, and the results download together as a single ZIP file — no upload queues, and no need to save each photo one by one.
Works Completely Offline
Once the web app loads in your browser, you can disconnect from Wi-Fi or cellular networks and continue cropping images anywhere. It is a lightweight, install-free web app with Progressive Web App (PWA) support.
About Remember Adjustments For Future Sessions
- Off by default: nothing is remembered unless you tick “Remember Adjustments For Future” under the Center and Reset buttons.
- What it remembers: once ticked, your zoom, move, straighten, border, background and download size settings are reused the next time you add a photo or visit this page.
- Your privacy: these settings are saved in your own browser and never on our server.
- Easy to clear: untick the box at any time to erase the saved settings.
Frequently Asked Questions
Is this image cropper really free to use?
Yes, this tool is 100% free with no hidden fees, paid upgrades, or daily usage limits.
Are my photos uploaded to any server?
No. Your images never leave your computer or mobile device. All image cropping and processing happen locally within your web browser using client-side JavaScript.
Does this tool work without an internet connection?
Yes. Once you open the web page in your browser, you can turn off your internet connection or go offline, and the image cropping functionality will continue to work seamlessly.
How many images can I crop at once?
Up to 100 images in a single batch. Add your first photo, click Crop many photos at once (ZIP), pick a size, and choose the rest. The same crop, border, and background are applied to every photo, and they download together as one ZIP file. Because the work is done by your own device rather than a remote server, there is no daily limit, so you can simply run another batch.
What image formats are supported?
The tool accepts the standard web image formats your browser can open, including JPG/JPEG, PNG, WebP, and GIF (an animated GIF uses its first frame). Other formats, such as HEIC, work only if your browser can display them. Cropped photos are always saved as PNG.
