About Batch Image Resizer
What this page solves
Batch Image Resizer solves the privacy and friction problem of typical online tools — it never uploads, never asks for a signup, and runs in your browser.
Batch Image Resizer is a free in-browser image tool that lets you resize multiple images at once without uploading your photos to any server. It is built for designers, content creators, marketers, and everyday users who need quick, private image edits — whether you are preparing assets for a website, resizing photos for social media, or compressing files before sending them by email. All processing uses your browser's Canvas and Web APIs, so your images stay on your device the entire time. Output downloads directly to your device — there is no "share link" the recipient (or the service) can revisit later. Nothing you load into Batch Image Resizer is uploaded: the file or text is read with the browser's own FileReader and processed in page memory, so the work finishes even if your connection drops mid-task. Because the processing is local, Batch Image Resizer is usable on locked-down corporate laptops and school networks where uploading work files to a third-party service is a policy violation. There are no watermarks, no quality compromises from third-party servers, and no waiting in upload queues. Batch Image Resizer is part of our Image Tools suite — a unified set of tools for every step of an image workflow. If you also need a complementary utility, try our Image Resizer. It is free, has no signup, and works with the formats you actually use: JPG, PNG, WebP, GIF, SVG, and BMP.
