Common ways to use this tool

WebP to PNG without uploading

Convert WebP files to PNG locally, including batch workflows for multiple images.

HEIC to JPG without uploading

Open HEIC images and export browser-friendly JPEG or PNG versions on your device.

Batch image converter with no upload

Convert up to 50 PNG, JPEG, WebP, AVIF, HEIC, SVG, or other supported images in one batch.

Image, audio, and video converter

Use one local converter for common image, audio, and video formats instead of separate upload services.

Convert H.264 to H.265 without uploading

Choose H.265 in the video settings and keep the original resolution and frame rate, or adjust them before export.

Universal Converter

Convert images, audio, or video without uploading your files. Choose an output format, preview the files, and save the results. Each batch contains one media type: up to 50 images, 20 audio files, or 8 videos.

Supported formats

Image input: PNG, JPEG, WebP, AVIF, GIF, BMP, HEIC, SVG. TIFF is not supported.
AVIF export is available only when the browser provides an AVIF encoder.
Audio: MP3, WAV, M4A, AAC, OGG, FLAC
Video: MP4, WebM, MOV, AVI, MKV and related common containers

Why it is different

One tool handles raster images, vector SVG input, audio, and video.
Preview files before converting and download results individually or as a batch.
Analyzes video resolution, frame rate, and bitrate before explicit H.264 to H.265 or H.265 to H.264 conversion.
Resize images and video, or adjust audio quality before export.

Privacy and local processing

Conversion runs locally in the browser. The workspace is built around local processing rather than file upload to a backend converter.

FAQ

Can I batch convert files?

Yes. A batch can contain up to 50 images, 20 audio files, or 8 videos. Do not mix media types in the same batch.

Can I resize on export?

Yes. Image export supports max-dimension and relative scale resizing. Video export also supports resize controls when re-encoding is needed.

Does it preserve source settings by default?

Video keeps its original resolution and frame rate unless you change them. When re-encoding is needed, the converter uses the source bitrate to choose an initial quality setting.

Can it convert H.264 video to H.265 and back?

Yes. Choose H.264 or H.265 in the video settings. Resolution and frame rate stay unchanged unless you edit them. If the selected codec cannot be encoded in your browser, the converter reports an error.
