FAQ
- How do you determine the order of the merged images?
- We join PNGs in the exact sequence you upload them. To change the order, remove the files and add them back in your desired sequence.
- What happens if my screenshots have different sizes?
- We align vertical images by width and horizontal ones by height. If you select "Scale to narrowest/shortest," we scale larger images down. If you select "Scale to widest/tallest," we pad smaller images with transparent space.
- Do you preserve transparent PNG backgrounds?
- Yes. We save the final output as a PNG, keeping all original transparent regions intact. Any border space created by different image sizes also remains transparent.
- Do you upload my PNGs to a server?
- No. We merge your images locally on your device. We never upload files to a server, and they clear from memory as soon as you close the page.
