Frequently asked questions
Are widths matched?
Yes: each image is scaled proportionally to the widest one so there are no steps.
Any height limit?
Browsers cap giant canvases (~16k px per side). With dozens of captures, join in batches.
Which formats are accepted?
JPG, PNG, WEBP, AVIF, BMP and GIF (first frame). The output keeps the original format when possible.
Is my image uploaded to a server?
No. All processing happens on your device using the browser itself; the image never leaves it.
