Add an image or a frame to a GIF

GIFmeta can add new frames to an existing GIF: an image file (PNG, JPEG or WebP) or a copy of a frame that is already there. The image must have the same size as the GIF.

With the desktop app

Insert an image

1. Open the GIF and select the frame the image should come after.
2. Click ➕ Insert image… (or press I) and pick one or more images — or drop the files onto the window.
3. The new frames are marked new. Change their delay, drag them into place, and 💾 Save.

Duplicate a frame — select it and press D. The copy (marked copy) goes right after it. Great for holding a moment longer or building a boomerang.

Remove an inserted image or a copy with ⌫.

With the command line

# insert logo.png before frame 3
gifmeta mod input.gif --insert 3=logo.png -o with-logo.gif

# append an end card (10 frames → before frame 10 = at the end), shown for 2 s
gifmeta mod input.gif --insert 10=the-end.png --insert-delay 200 -o with-end.gif

# replace frame 3: insert before it and delete it
gifmeta mod input.gif --insert 3=fixed.png --delete 3 -o replaced.gif

# hold the first frame three times as long
gifmeta mod input.gif --duplicate 0,0 -o hold.gif

Repeat --insert for several images. Without --insert-delay, an inserted image uses the delay of the frame it is inserted before.

Good to know

• Wrong size? GIFmeta tells you the image and GIF sizes. Resize the image first (fit / crop options may come later).
• Inserted images are stored as full frames. Images with more than 256 colours are colour-reduced.
• Frames after the inserted image that depended on the old neighbour are rebuilt, so the GIF still plays correctly.
