You search for an "online image resizer," but most of them have two major flaws:</p> <ul> <li>They force you to upload your sensitive data to their servers.</li> <li>You have to manually look up dimensions for every platform.</li> </ul> <p>I decided to fix this by building <strong><a href="https://probatchresizer.com" rel="noopener noreferrer">ProBatchResizer</a>.</strong></p> <p>I spend tons of time to build this web tool in this Ai era. Then blen it in with wordpress. This is hell of a effort i put just to make sure you can get optimal &amp; fast result.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fc3d72grsrby3wu8ixmet.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fc3d72grsrby3wu8ixmet.png" alt=" "></a></p> <p><strong>Privacy First: No Server Uploads</strong><br> The biggest differentiator here is security. Using WebAssembly (WASM) and multi-threading, ProBatchResizer does all the heavy lifting directly in your browser. Your images never leave your device. It’s as fast as a desktop app but works in your tab.</p> <p><strong>130+ Presets: Stop Googling Dimensions</strong><br> The most tedious part of resizing is remembering the exact pixels for a LinkedIn banner vs. an Amazon product listing. I’ve integrated over 130 popular presets so you can batch-process images in seconds for:<br> Corporate &amp; Marketing: Business cards, letterheads, and email headers.<br> Social Media: Perfectly sized assets for Instagram, TikTok, LinkedIn, and X.</p> <p> <iframe src="https://www.youtube.com/embed/9b0ZE1a30zI"> </iframe> </p> <ul> <li>Advertising: Standard sizes for Google Ads, Facebook Ads, and banners.</li> <li>Web &amp; Development: Favicons, Hero sections, and OpenGraph images.</li> <li>Print: High-precision resizing in cm, mm, and inches.</li> </ul> <p><strong>Key Features for Developers &amp; Creators:</strong></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F410lhug4lfdzouv5ubk4.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F410lhug4lfdzouv5ubk4.png" alt=" "></a></p> <ul> <li>Blazing Fast: Multi-threaded processing means instant results even for large batches.</li> <li>Pro Control: Convert between JPG, PNG, and WEBP with smart compression to keep files small but sharp.</li> <li>Polish Before Export: Integrated tools to <strong>crop, flip,</strong> and <strong>rotate</strong> before you hit download.</li> </ul> <p>I built this to be the last image resizer you’ll ever need to bookmark. </p> <p>I'd love to hear your thoughts on the performance or if there are any specific presets you think I should add!</p> <p>Check it out.</p> imageresize productivity
