What file formats do you support?

We support over 100 file formats including images (JPG, PNG, GIF, WebP, TIFF), documents (PDF, DOC, DOCX, TXT), videos (MP4, AVI, MOV), audio (MP3, WAV, FLAC), and many more specialized formats.

Yes, absolutely. We use enterprise-grade encryption for all file transfers. Your files are automatically deleted from our servers after conversion, and we never store or access your personal data.

What is the maximum file size?

The maximum file size for free users is 100MB per file. Premium users can convert files up to 1GB. For larger files, we recommend our batch processing feature.

How long does conversion take?

Most files convert in under 30 seconds. The exact time depends on file size and format complexity. Our advanced algorithms ensure the fastest possible conversion while maintaining quality.

Can I convert multiple files at once?

Yes! Our batch processing feature allows you to upload and convert up to 50 files simultaneously. This is perfect for bulk conversions and saves significant time.

Do I need to create an account?

No account is required for basic conversions. However, creating a free account gives you access to batch processing, file history, and priority support.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare JFIF for Palette Mapping

Inspect JFIF color gamut and convert to sRGB if your workflow expects web colors
Apply local contrast or gradient smoothing to JFIF to reduce posterization after quantization
Crop JFIF to remove uniform matte borders that could become unintended transparent indices
Flatten layered edits before exporting JFIF so raster pixels match final appearance
Remove superfluous EXIF rotations by baking orientation into pixels prior to conversion

Manage GIF Encoding & Size

Choose adaptive palette when converting photographic JFIF to minimize color loss in highlights
Use dithering between JFIF RGB and GIF indexed palette to preserve perceived gradients
Limit GIF dimensions when converting high-resolution JFIF to keep file size practical
Prefer per-frame palettes for simple graphics; for animated assemblies, consider a shared palette for smaller output
Compress final GIF in a ZIP for distribution if storing multiple converted files

Verify Color and Artifacts

Compare JFIF and GIF at 100% zoom to spot banding introduced by palette reduction
Check critical color matches against proofed sRGB targets after conversion
Inspect edges and thin details from JFIF for dithering-induced noise in GIF
Open GIF in target browser and in your editor to confirm rendering parity with JFIF
If GIF looks posterized, re-convert with alternate palette or increased dithering

Preserve Workflow Integrity

Keep original JFIF files for archival and reprocessing with different color/palette settings
Document any manual palette or dithering choices used when converting JFIF to GIF
Batch-convert JFIF in consistent groups to maintain visual consistency across a set
Avoid relying on GIF for color-critical prints; use TIFF or PNG from original JFIF instead
Promptly validate animated GIF timing if assembling multiple JFIF frames to ensure playback accuracy

Fast Processing

Close unused tabs for maximum throughput.

Client-Side Privacy

No media leaves your device.

Broad Compatibility

Output files work across all operating systems.

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
