How browser-based image compression works
When you drop an image into the tool, the browser decodes it into a Canvas element. Canvas draws pixels into a raw framebuffer that can then be re-encoded as JPG, PNG, or WEBP with a quality parameter you control. Because we redraw and re-encode from scratch, every EXIF tag, thumbnail, and metadata block from the original file is dropped — which improves privacy and shaves extra bytes.
There is no upload step. The file never leaves your device. The same approach works fully offline, which is why the tool keeps running if you disconnect from the internet after loading the page.
Choosing quality vs. size
JPG and WEBP are lossy: lower quality means smaller files and more visible artefacts. As a rule of thumb, 80–90% is the sweet spot for photos, 70–80% works for web hero images, and 60–70% is fine for thumbnails or email attachments.
PNG is lossless, so the quality slider only affects compression effort — the pixels stay pixel-perfect but the file may not shrink as dramatically. If your PNG contains a photograph rather than a logo or screenshot, converting to WEBP or JPG usually cuts the file size by 60–90% with no visible difference.
Why this is safer than online compressors
Most free online compressors ask you to upload each image to their server, process it there, and then let you download the result. That means a copy of your file exists on infrastructure you don't control. Vrinda Tools' Image Studio never uploads anything — the same compression engine runs directly inside your browser. Your photos, screenshots, and client work stay on your device.
