Resize an image to a maximum dimension with proper resampling, for smooth downscales without jagged edges or moiré. Aspect ratio is preserved, and nothing is uploaded.
How it works
- Drop an image, or many, or a ZIP, for a batch.
- Pick the format and either a quality level, a maximum dimension, or an exact target file size.
- Convert & download. The panel shows the real output size and dimensions.
Questions
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- How does "compress to target size" work?
- The tool searches the quality setting until the output lands under your target at the highest quality that fits, using at most a handful of encode passes, all local. If even the lowest quality overshoots, it steps the resolution down and says so.
- Why is AVIF not offered?
- Browsers can decode AVIF but cannot encode it from a canvas today. Rather than shipping a broken option, it is not offered; WebP typically gets most of the size benefit.
- Does converting remove metadata?
- Yes. Re-encoding drops EXIF and GPS data as a side effect, and the panel says so. For lossless metadata removal that keeps the original pixels, use the metadata remover instead.
