About Image Resizer
Whether you're prepping product photos for a marketplace that caps images at 2000 pixels, shrinking screenshots to fit a support ticket, or building thumbnails for a blog, resizing dozens of images by hand in a desktop app is a chore. Filenify's Image Resizer accepts JPG, PNG, WebP, GIF, and BMP, lets you resize by exact pixel dimensions or a percentage, and locks aspect ratio by default so nothing gets stretched. High-quality bicubic-style downscaling (via the Canvas API's high-quality resampler) keeps edges crisp instead of the jagged look you get from naive box filters. Everything runs in your browser — no upload, no queue, no daily quota — and you can change the output format on the fly so a batch of PNG mockups can leave as space-saving WebP or web-friendly JPG.
