Questions and answers
How do I resize a photo to a size in KB?
Open the Size tab, choose your dimensions, and type the largest file size in the Max, in KB box. PicWorkshop lowers the quality as needed so the file stays under the limit, and shows the expected size before you save.
What is the difference between Custom size, Percent and Ready-made?
Custom size lets you type exact numbers. Percent scales the photo by a percentage. Ready-made gives you common sizes and ratios, such as social media and passport sizes.
Can I resize many photos at once?
Yes. Add all of them, set the size once, and download them together as a ZIP.
Are my photos uploaded anywhere?
No. All work happens in your browser on your device, and your photos are not sent to our servers. While you move between pages of this site, they are kept briefly in your browser's temporary storage and removed when you close the tab.
