🔍 GIF Upscaler
Enlarge any animated GIF to 2x, 3x, 4x, or a custom size — fully in your browser, with no file upload and no account needed.
About
This tool enlarges animated GIFs entirely on your device — your file never leaves the browser. Upload any animated GIF and choose a scale factor: 2x, 3x, or 4x presets, or enter any custom multiplier you need. Two interpolation algorithms are available. Nearest Neighbor produces pixel-perfect sharp edges with no blurring, making it the ideal choice for pixel art, retro sprites, and low-resolution icons where you want clean, hard edges. Smooth interpolation applies high-quality bicubic-style blending, which works well for photos, illustrations, and gradients where you want a natural, fluid enlargement rather than a blocky result. Additional output options include palette color count (256, 128, 64, or 32 colors), a Floyd–Steinberg dithering toggle to improve gradient rendering within the palette constraint, and a preserve-transparency option to keep transparent pixels intact. The tool processes every frame individually and maintains the original frame timing and loop count so the animation plays back at the same speed as the source GIF.
How to use
- Drop an animated GIF onto the upload area, or click to browse and select one from your device.
- Choose a scale factor — 2x, 3x, or 4x — or type a custom multiplier for precise control.
- Select an interpolation algorithm: Nearest Neighbor for pixel-perfect sharpness (pixel art, retro sprites), or Smooth for natural-looking enlargement (photos, gradients).
- Set palette color count (256 / 128 / 64 / 32), enable or disable Floyd–Steinberg dithering, and choose whether to preserve transparency.
- Click Upscale to process all frames. Preview the result and click Download to save the enlarged GIF.
FAQ
- Does my GIF get uploaded to a server?
- No. All frame decoding and scaling is done in your browser using the Canvas API. Your GIF file never leaves your device.
- Which algorithm should I use — Nearest Neighbor or Smooth?
- Use Nearest Neighbor for pixel art, retro sprites, and graphics with hard edges — it keeps every pixel sharp without blurring. Use Smooth for photos, illustrations, and gradients where you want a natural-looking result without visible pixel blocks.
- Will the animation speed change after upscaling?
- No. The tool preserves the original frame delay and loop count from the source GIF, so the animation plays back at the same speed.
- What does the palette color count setting do?
- GIF supports up to 256 colors per frame. Lowering the color count (128, 64, 32) reduces the output file size at the cost of some color accuracy. Use 256 for the best color quality and smaller values if file size matters more.
- Is there a maximum file size or frame count?
- There is no hard limit enforced by the tool, but very large GIFs with many frames may be slow to process or exceed your browser's available memory. For best performance, use reasonably sized source GIFs.
