Choose images or a folder
Select individual PNG, JPEG, or WebP images, or choose a folder to include its nested folders in the export.
Compress a folder of images, resize them in one pass, and download the results together. Your files stay in this browser from start to finish.
PNG, JPEG, and WebP are supported. Folder paths are retained in the ZIP.
Keep the original proportions. Images are never enlarged.
Original formats are preserved; JPEG, PNG, and WebP inputs are supported.
Tip: Browser PNG export is lossless. To shrink PNG file sizes by 60–85%, switch Output Format to WebP or JPEG.
Presets are maximum bounds, not crop sizes. Each image keeps its original aspect ratio.
Used for WebP and JPEG. PNG uses lossless compression.
Compress a few images or a whole working folder. The tool keeps the directory structure, applies your size and format settings, then packages the results into one ZIP.
Select individual PNG, JPEG, or WebP images, or choose a folder to include its nested folders in the export.
Choose a maximum width and height, output format, and JPEG or WebP quality. Images keep their proportions and are never enlarged.
Review the queue and start compression. The finished ZIP keeps the selected folder’s paths and updated file extensions.
Subfolders stay in place, so a large batch remains easy to find after export.
Illustrative folder layout. Output dimensions and file sizes depend on your chosen settings and source images.
No. Image decoding, resizing, and encoding run in your browser. The page loads JSZip from a CDN to create the download, but the selected image files are not sent to a server.
Not always. Resizing or converting to WebP/JPEG often reduces size, while PNG is lossless and may remain similar or grow. Compare the exported files for your particular artwork.
PNG and WebP can retain transparency. JPEG does not support it, so transparent areas are filled with white when you choose JPEG output.
Yes. Folder paths are included in the ZIP, and resizing uses one proportional scale for both dimensions. The tool will not enlarge smaller images.
