Drag and drop your images here
WebP, HEIC, JPG, PNG, or GIF
Select or paste multiple images. Animated GIFs will be converted to a single static frame.
Up to 50 images, 100 MB per batch, and 40 megapixels per image. Your files stay on your device.
Which sizes do you need?
Original proportions will be preserved. Specify max width, max height, or both. Smaller images will not be enlarged.
Each image will receive a version for each target size. Limit of 12 sizes; dimensions from 1 to 8192 px.
Choose output format for versions
100% provides maximum visual quality with minimal compression. Lower the slider to target smaller file sizes. JPG remains a lossy format even at 100%. Transparent areas receive a solid white background.
24-bit preserves colors with an alpha channel for transparency. 8-bit uses an indexed palette and may alter subtle gradients.
Each image folder will contain the untouched original with _original in its filename, alongside versions labeled by their actual dimensions, such as photo_512x341.jpg.
