Inspect animated GIF internals: dimensions, frame count, delays, palettes, and disposal methods. Export metadata as JSON.

Flip the frame order of an animated GIF so it plays backwards, keeping the original size and per-frame timing intact.

Set a speed percentage and the frame delays get rewritten, so the animation runs faster or slower without re-encoding a single pixel.

Type a start and end time in seconds and keep only the frames in between, trimming a long animation down to the part that matters.

Enter a new width and every frame is scaled to match, so the animation survives the resize. Leave height blank to hold the aspect ratio.

Set an X, Y, width, and height crop box and every frame gets cut to it. Handy for chopping black bars or a corner watermark off a loop.

Turn an animation 90, 180, or 270 degrees, or mirror it horizontally or vertically. All frames rotate together so the loop stays in sync.

Append the reversed frames to the end so the animation runs forward then back, giving a boomerang loop with no visible jump at the seam.

Scramble the frame order for a glitchy remix of an animation. Each frame keeps its own delay, only the sequence gets shuffled.

Give a target length in seconds and the loop repeats until it gets there, for when a two-second clip has to fill a fixed slot.

Re-encode an animated GIF as animated WebP, which usually lands under half the file size while keeping the same frames and timing.

Move an animation to APNG when 256 colors and hard-edged transparency are not enough. APNG carries full alpha and 24-bit color per frame.

Give a single photo a zoom, pan, or pulse move and export it as a looping GIF. Frame count and delay control how slow the motion reads.

Enter the rows and columns of a sprite sheet and it gets sliced on that grid into separate PNG tiles at the original pixel size.

Redraw a photo without its EXIF block, dropping GPS coordinates, camera model, and capture time before you post it. The pixels stay untouched.

Drop two images and get them laid out side by side at full resolution on one canvas, which makes before and after differences easy to spot.

Combine photos into a horizontal strip, a vertical stack, or a 2x2 grid with an adjustable gap, then save the whole arrangement as one image.

Clip an image into a rounded rectangle. Set the corner radius anywhere from 1 to 50 percent and get a PNG back with the corners knocked out transparent.

Fit a headshot to the US 2 by 2 inch or EU 35 by 45 mm passport size, centered on white at print resolution and ready to send to a photo lab.

Stack a set of images into an animated PNG, or hand it a single photo and let a zoom, pan, or pulse motion generate the frames for you.

Turn a stack of images into an endlessly looping animated WebP at the frame delay you choose, and land a much smaller file than the same GIF.

Set how many times an animated GIF repeats before it stops. Enter 0 to loop forever, 1 to play once and freeze, or any count in between.

Break an animated GIF back into its individual frames, review every one as a thumbnail, and save them all as numbered PNG files in one click.

Merge two animated GIFs into one, side by side or stacked. The shorter clip loops so both keep playing until the longer one finishes.

Lay a caption bar across the bottom of every frame of a GIF. Type the line, pick the font size, and export the meme in one pass.

Recolor every frame of a GIF at once with grayscale, sepia, invert, or blur, then re-encode the animation with the new look baked in.

Read what an image file actually is before you use it: format, exact byte size, and pixel dimensions, all without the photo leaving your machine.

Scale a photo up to four times its original size with high quality resampling. Set the percentage, check the preview, and save the bigger file.

Redraw a photo as black dots on white, the way newspapers used to print pictures. Dial the dot density from coarse and punchy to fine and subtle.

Reshape a photo to 16:9, 1:1, or any ratio you type in. Letterbox mode pads the gaps with white, crop mode trims whatever hangs over the edge.

Assemble a set of images into an animated JPEG XL, or animate one photo with zoom and pan motion. Set the frame delay, then download the file.

Build a looping animated AVIF from a batch of images. Same motion as a GIF at a fraction of the byte count, with full color instead of 256.

Swap an animated GIF for a JPEG XL that carries the same picture in far fewer bytes. Drop the file in, wait for the encode, take the result.

APNG keeps full color and alpha, but plenty of apps only read GIF. Decode the animated PNG and download a 480 pixel wide GIF at 10 fps.

MNG is a dead animation format that almost no viewer opens today. Drop the old file in and get a standard GIF, 480 pixels wide at 10 fps.

Lay every frame of an animated GIF out in a single grid image, ready for a CSS sprite animation or a game engine atlas.

Cut a long animated GIF into smaller pieces by frame range and download each part on its own.

Rebuild a GIF that stopped animating. Re-encode the frames, reset the loop flag, and download a copy players will actually open.

Crop and resize an animated GIF to the 1:1 square Instagram expects, then download it sized and ready to post.

Put the classic white caption bar above a GIF instead of over it, so the text stays readable and the frame stays uncovered.
