Frequently Asked Questions
About the resize & compress tool
Which image formats can I resize or compress?
You can upload HEIC, JPG, PNG, or WebP images. Download the result as JPG, WebP, or PNG.
Will resizing make my image look worse?
Reducing the dimensions removes pixels, so very small outputs can lose detail. For JPG and WebP, the quality setting also controls compression; PNG remains lossless.
How does the target file size option work?
Enter the maximum file size and the tool adjusts JPG or WebP quality to get as close as possible without going over it.
Are my images uploaded?
No. Processing happens locally in your browser, so your images are never sent to a server.
Can I resize several images in one batch?
Yes. Select multiple images, choose your settings, and process them together. Download files individually or as a ZIP.
