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.

Source vs Target Format

Key technical differences between formats

Feature	Source Format	Target Format
Compression	High precision, often HDR-specific encodings	Lossy or lossless block-based WebP
File Size	Large (high bit depth)	Smaller (optimized for web)
Quality	Very high dynamic range fidelity	Perceptually optimized SDR fidelity
Transparency	Supported in some HDR formats	Supported as 8-bit alpha
Metadata	Rich EXIF/XMP, LUTs, camera data	Basic EXIF/ICC embedding possible
Primary Use	Editing, grading, archiving	Web delivery and fast rendering

How to Convert Files

Follow these simple steps to convert your files

Upload Source File

Select or drag and drop your HDR (.hdr/.exr) file into the interface.

Adjust Settings

Choose tone mapping method, quality level, and desired output dimensions.

Convert

Click convert to apply tone mapping and encode into WebP in the browser.

Download Result

Save the WebP file or ZIP bundle; verify color and transparency on target browsers.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare HDR for Tone Mapping

Adjust exposure or apply local contrast in HDR editor to control highlight clipping during tone mapping
Flatten layered edits to a single RGB(A) image to avoid unexpected compositing when rasterizing to WebP
Remove or bake LUTs and color transforms into pixels so the converter maps final colors predictably
Resize to final display dimensions before conversion to reduce banding introduced by resampling
Export a 16-bit TIFF preview if you need to compare high-precision intermediate results before WebP encoding

Configure WebP Encoding

Choose lossless WebP for archival-looking SDR copies when preserving fine gradients matters
Increase quality parameter for lossy WebP to reduce posterization in highlight transitions
Enable alpha channel export only if original HDR contains meaningful transparency masks
Set chroma subsampling cautiously; aggressive subsampling can blur saturated HDR highlights
Use progressive resizing sequences to evaluate file-size vs visual trade-offs before batch export

Validate Across Targets

Preview converted WebP on representative browsers to check for gamma and highlight shifts
Compare source and WebP histograms to detect lost midtone or highlight detail after tone mapping
Inspect edges at 100% zoom to catch compression ringing introduced by high compression ratios
Verify embedded metadata fields if your pipeline depends on EXIF or copyright tags
Test mobile rendering since device tone-mapping and browser color management vary

Pipeline Reliability and Privacy

Process sensitive HDR files in-client to avoid server-side exposure when privacy is required
Split large batches into groups of 20–50 to reduce memory pressure and avoid timeouts
Automate checks that confirm presence of alpha or expected color profile after conversion
Maintain originals in HDR archive format for re-editing; WebP is for delivery, not master storage
Schedule bulk conversions during off-peak hours to ensure consistent CPU availability for tone mapping

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.
