How to use
- Add your images. Drag and drop one or many images, or click to browse and select files from your device.
- Choose how to resize. Set exact pixel dimensions, a percentage, or a longest-side value, or pick a social media preset like Instagram or YouTube.
- Set your options. Lock the aspect ratio, enable don't-enlarge to avoid upscaling, and choose the output format and quality.
- Resize and download. Run the resize locally with Lanczos resampling, then download each image or grab the whole batch as a ZIP.
Features
- Flexible resize modes. Resize by exact pixels, by percentage, or by longest side, whichever fits how you think about the target size.
- High-quality Lanczos resampling. A Lanczos filter keeps resized images sharp and clean instead of the soft, blocky look of a basic browser resize.
- Social media presets. One-click sizes for Instagram, YouTube, Facebook, X, LinkedIn and TikTok so your images fit each platform perfectly.
- Aspect ratio and no-upscale. Lock the aspect ratio to avoid stretching, and enable don't-enlarge so small images are never blown up and blurred.
- Batch, no upload, no limits. Unlike TinyPNG, iLoveIMG or Convertio, resize whole batches with format and quality control, all without leaving your browser.
When to use it
- Resize a photo to the exact Instagram, YouTube or LinkedIn dimensions with a single preset.
- Bulk-resize a folder of product images to the same width before uploading to an online store.
- Shrink oversized phone photos to a sensible size so pages load faster and files stay small.
- Resize by longest side to fit an upload limit without worrying about exact width and height.
- Downscale screenshots to a fixed percentage for documentation while keeping text readable.
