GOOD TO KNOW
Quick answers.
Can I make a GIF from several images?
Yes. Add up to 12 images, reorder them, and set how long each appears.
Can I edit an existing animated GIF?
Yes when your browser supports animated image decoding. SigPop unpacks its frames into the timeline; otherwise it clearly reports that the visible frame was used.
What is Advanced mode?
Basic mode keeps the workflow short. Advanced mode unlocks per-image timing, transforms, custom dimensions and signature text.
Can I move a project to another computer?
Use Save project to download a portable .sigpop file, then choose Open project on the other device.
Will the download stay animated?
Yes. SigPop downloads a real GIF89a .gif file.
Does my image or draft leave my computer?
No. Reading, autosave, rendering, encoding, and counters stay in this browser.
How accurate is the size estimate?
It is a range. Image complexity affects compression, so the verified size appears after export.
Which preset should I use?
Use Exclaimer safe for 300 KB, Email compact for most signatures, or Custom for exact dimensions.
Why is there a first-frame preview?
Some older clients only display the first frame.
Can I use any image I find online?
Only use images you created, licensed, or have permission to use.
