How do I reverse a GIF?

Upload your GIF, image sequence, or video clip, then enable the Reverse toggle before clicking Create GIF. The output will play in the opposite direction. This works with all three input types.

Can I set different speeds for different frames?

Yes. Unlike most GIF tools that only offer a global delay, this editor lets you set an individual delay (in milliseconds) for each frame. Click any frame thumbnail to adjust its timing independently — useful for tutorial GIFs where certain steps need more viewing time.

What is the difference between this tool and Images to GIF or Video to GIF?

Images to GIF is focused on turning a photo sequence into an animation — ideal for product showcases and slideshows. Video to GIF is focused on trimming and converting a video clip into a GIF. This GIF Editor & Maker adds editing capabilities on top: import an existing GIF, apply per-frame timing, reverse playback, and crossfade transitions. Think of it as the editor, while the other two are converters.

Can I upload a ZIP file of images?

Yes. You can upload a ZIP archive containing your image frames — the tool will extract and import all images automatically, saving you from selecting files one by one.

What if my images are different sizes?

For best results, standardize your frame sizes before uploading — especially if using the crossfade effect. You can use our Bulk Image Cropper to resize multiple images to the same dimensions in one step.

Does this GIF editor add a watermark?

No. BulkPicTools GIF Editor is completely free and does not add any watermark, logo, or branding to your output files. The GIF you download is exactly what you created — clean and ready to share. No account required.

How do I make a GIF small enough for Discord (under 8MB)?

Discord limits GIF uploads to 8MB for free accounts (50MB for Nitro). To stay under 8MB: (1) Set the output width to 480px or smaller.. (2) Increase the frame delay to 0.1s or above.. (3) Delete unnecessary frames before exporting.. (4) If still too large, run the output through our GIF Compressor..

Is my data kept private?

Yes, completely. All processing happens locally inside your browser — your images, GIF files, and video clips are never uploaded to our servers. This means your personal and sensitive content stays on your device at all times.

Can I use this tool on my phone?

Yes. The GIF Editor works on any modern browser, including Chrome and Safari on iOS and Android. Note that processing large video files may be slower on mobile — for video-to-GIF conversion, a desktop browser gives the best results.

Guides & Tips

How to Edit an Existing GIF Online

1. Upload Your GIF File
Drag and drop any .gif file onto the upload area. The tool will automatically split it into individual frames displayed as thumbnails — no extra software needed.
2. Delete or Reorder Frames
Click the remove icon on any thumbnail to delete unwanted frames. Drag thumbnails to rearrange the sequence. This is useful for cutting out repeated or irrelevant frames from a downloaded GIF.
3. Set Per-Frame Delay
Click any frame thumbnail to set its individual display time in milliseconds. Unlike global-speed tools, you can make one frame linger for 1s while the rest play at 0.08s — ideal for tutorial GIFs where one step needs more reading time.
4. Export and Download
Click Create GIF. Your edited file downloads immediately with no watermark. The entire process happens in your browser — your GIF is never uploaded to any server.

How to Reverse a GIF Online

1. Upload Your Source
Upload a GIF file, an image sequence (JPG, PNG, WebP), or a video clip (MP4, MOV, WebM). All three input types support reverse playback.
2. Enable Reverse
Toggle the Reverse switch in the settings panel before generating.
3. Create and Download
Click Create GIF — the animation will play in the opposite direction. No watermark is added at any point.
Tip: Boomerang Loop
To create a seamless boomerang effect (forward then backward), upload your frames twice — once in normal order, then again in reverse order. The GIF will play through forward and backward in a single loop.

How to Add Crossfade Transitions to a GIF

1. Upload Your Image Sequence
Upload your JPG, PNG, or WebP images. Arrange them in the correct order by dragging thumbnails.
2. Enable Crossfade
Toggle the Crossfade option. You can adjust the transition duration in milliseconds — 200–400ms works well for most slideshows. Transition frames are generated automatically between each of your original frames.
3. Generate and Download
Click Create GIF. The output will have smooth fade transitions between every frame — no abrupt cuts.
Tip: Matching Frame Sizes
Crossfade works best when all frames are the same dimensions. If your images are different sizes, standardize them first. Use our Bulk Image Cropper to resize all frames to the same size in one step.

Tips for Smaller GIF File Size

1. Reduce the output width — halving the width reduces file size by roughly 75%. Need to compress an existing GIF for Discord?
2. Increase the frame delay — a delay of 0.15s instead of 0.05s can cut file size in half with minimal visual impact.
3. Trim unnecessary frames — delete any frames that don't add to the animation.
4. For Discord, aim for under 8MB (free accounts) or 50MB (Nitro). Use the resize option to hit this target.

How to use
