How to Compress, Resize or Convert Many Images at Once
When a website, a form or a shop listing needs dozens of photos in the same size and format, doing them one by one takes too long. Add them all here, set the format, quality, target size or dimensions once, and every photo is processed with the same settings.
- 01
Add Your Images
Choose or drag in as many PNG, JPEG, WebP, AVIF, HEIC (iPhone), GIF, SVG, BMP or TIFF images as you need. Each one appears in the queue with its size.
- 02
Choose the Settings
Pick an output format and quality, or a target file size in KB, and optionally a new width and height or a preset. The same settings apply to every photo.
- 03
Download as a ZIP
Run the batch, check each result and its new size in the queue, then download every processed image in one ZIP file.
Frequently Asked Questions
Answers about this tool.
How many images can I process at once?
There is no fixed limit. Photos are processed one after another on your device, so very large batches of big camera photos depend on how much memory your phone or computer has.
Can I compress every image to a size in KB?
Yes. Set a minimum and maximum size in KB (for example 50 to 100 KB) and each image is compressed to fit inside that range, which suits upload forms that set a file-size limit.
Which formats can I convert to?
WebP, AVIF, PNG, JPEG, BMP, TIFF, GIF and ICO. HEIC photos from iPhones can be added too and are converted to the format you choose.
Can I resize all images to the same dimensions?
Yes. Enter a width and height, or pick a preset, in the Dimensions settings and every image in the batch is resized the same way.
Are my images uploaded to a server?
Normally, no — your image is processed inside your browser on desktops, laptops, phones, and tablets. It is sent over an encrypted HTTPS connection to our server only when you export a .ico favicon, use an exam / target file-size preset, edit a phone photo larger than 12 megapixels, or if your browser cannot process the image itself; it is then processed in memory and returned immediately, and never stored, logged, or shared.
