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.

Why Choose Our Converter?

Efficiently convert legacy JBG images to modern AVIF with control over quality, size, and compatibility for professional pipelines

Fast JBG to AVIF Processing

Convert legacy JBG scans quickly in-browser with minimal wait times for single images and small batches.

High Visual Fidelity

AVIF encoding preserves perceptual detail far better than many legacy formats at similar file sizes.

Modern Browser Targets

Produce AVIF outputs optimized for current Chrome, Firefox and Safari builds to improve web delivery.

Client-Side Processing

Files are decoded and encoded in the browser memory so original images do not leave the user device.

Adjustable Encoding

Fine-tune AVIF compression level and color options to balance file size and photographic quality.

Preserve Visible Detail

Raster content from JBG is faithfully decoded then re-encoded into AVIF with tuned perceptual settings.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare JBG Scans

Inspect JBG pixel depth: confirm 8-bit vs higher before encoding decisions to avoid false color shifts
Deskew and crop JBG scans to remove scanner margins so AVIF encodes only needed pixels
Despeckle or denoise JBG in a pre-process step to reduce AVIF quantization amplification
Convert grayscale JBG to proper color space only when necessary to prevent unnecessary chroma data expansion
Export a lossless intermediate if the JBG contains multiple embedded pages you may need later

AVIF Encoding Strategy

Select AVIF quality presets: higher quality reduces compression artifacts on fine scan detail
Enable or disable chroma subsampling depending on text/sharp-edge priority to balance size and clarity
When preserving color, request ICC embedding if your workflow requires exact profile round-trip
Use two-pass or tuned encoder presets for consistent visual quality across a large batch of JBGs
For archival, prefer minimal quantization instead of relying solely on AVIF file size savings

Workflow Integration

Test AVIF output in target CMS or browser to ensure rendering matches source scanner intent
For automated pipelines, include a verification step to confirm EXIF/ICC retention when required
If downstream editing is expected, keep an editable TIFF/PNG master separate from the AVIF delivery copies
Use consistent file naming during JBG-to-AVIF batches to maintain traceability between original scans and outputs
Validate OCR pipelines after conversion because AVIF compression may soften small text strokes

Verification & Resource Management

Check alpha presence: if your JBG variant encodes masks, confirm whether the AVIF output contains an alpha plane
Monitor memory when converting large JBGs; split very large scans into smaller batches to avoid browser swaps
Keep originals locally until verification of color, metadata, and sharpness is complete
Compare histogram and edge detail at 100% zoom between JBG and AVIF to detect unwanted smoothing
Automate spot checks for metadata consistency if your archive policy requires EXIF or ICC retention

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.
