I built BulkImgConvert: compress, resize, crop & convert images 100% in your browser

Hi DEV community!

I kept running into the same annoyance: I had a batch of images to compress, resize, or convert, and every online tool I found meant uploading my files to some server first. So I built BulkImgConvert (https://bulkimgconvert.com), a free tool that does it all directly in the browser.

What it does

  • Compress images by quality, percentage, target size (in MB), or target resolution
  • Resize precisely or by ratio
  • Crop free-form or with presets
  • Convert between JPG, PNG, WEBP, AVIF, GIF, SVG and PDF (plus HEIC as input)
  • Batch processing, so you can do dozens of files at once

How it works

Everything runs client-side via the Canvas API. Nothing is ever uploaded to a server, your files never leave your device, and it still works offline once the page is loaded.

No account, no watermark, no limits. It's just a tool I wanted for myself and figured others might find useful too.

Would love any feedback, especially on formats or workflows I might be missing!
