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?

Fast, reliable conversion from RGB raster images to RGBA with clear control over alpha handling and color fidelity.

Lossless / Fast Conversion

Quickly add alpha channel to RGB bitmaps with minimal processing overhead and browser-side execution.

Maintain Color Fidelity

Preserves RGB channel values while introducing alpha; avoid re-encoding color channels where possible.

Broad Software Support

Output RGBA PNG or Web formats that are widely supported by modern editors and browsers.

Pixel-Accurate Alpha

Generate per-pixel transparency from masks or uniform alpha values with predictable raster results.

Client-Side Processing

Conversions run in the browser memory buffers to minimize data transfer and protect source imagery.

Custom Alpha Options

Choose global opacity, threshold-based masking, or import an external alpha mask for precise control.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare RGB Sources

Flatten layered exports before upload to ensure known pixel results in RGBA outputs
Convert wide-gamut RGB to sRGB if target displays lack color management to avoid shifts
Trim extraneous borders in RGB files so alpha masks align precisely with subject edges
Embed or export a separate mask when original transparency was stored in a different channel
Verify source bit-depth and avoid upsampling expecting extra tonal precision in RGBA

Target Encoding Choices

Select PNG-24 RGBA for maximum compatibility and lossless alpha preservation
Use WebP with alpha for smaller file sizes when modern browser support is required
Avoid re-encoding to JPEG after adding alpha since JPEG lacks transparency support
Enable compression level appropriate to alpha complexity to balance size versus fidelity
When targeting print workflows, prefer 16-bit-capable containers but verify encoder support

Verification & QA

Preview RGBA assets against representative UI backgrounds to validate compositing
Open exported files in a color-managed editor to confirm ICC profile behavior
Zoom to 100% to inspect semi-transparent edge anti-aliasing introduced by masks
Compare original RGB pixels to converted RGBA color channels to ensure no shift
Test outputs in target browsers and apps to catch platform-specific alpha blending

Workflow Reliability

Process batches in groups of 20-50 RGB images to avoid browser memory pressure
Keep original RGB masters archived to recover from unwanted alpha decisions
Close heavy background apps to leave sufficient RAM for in-browser conversion
If metadata is critical, export metadata separately because browser processing may drop it
Download and check one sample per batch before committing to large-scale exports

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.
