Honvert: Offline Converter

Victor Alonso Altamirano Izquierdo

About this app

Honvert converts your files right on your phone: images, GIFs, audio, video and PDFs. Everything is processed on your device.

YOUR FILES NEVER LEAVE YOUR PHONE

The app does not request the Internet permission, so it cannot upload or send your files.
No accounts, no sign-in, no ads, no tracking, no subscriptions.
Works offline, anywhere.
WHAT YOU CAN DO

Images: convert between JPG, PNG, WebP and BMP. Adjust quality, resize by percentage, and crop to an aspect ratio. Photos keep their correct orientation.
GIF: make GIFs from videos or existing GIFs. Set the frame rate, width, speed and crop.
Audio: convert between MP3, M4A, OGG, WAV and FLAC. Set the bitrate and change the speed.
Video: convert to MP4 or WebM. Choose the resolution, bitrate, speed and aspect ratio, and keep or remove the audio.
PDF: turn images into a PDF, merge or split PDFs, export pages as JPG or PNG, and compress PDFs.
KEEPS WORKING IN THE BACKGROUND Long conversions keep running while you use other apps. The progress notification shows how far along the conversion is, and you can cancel it from there.

GOOD TO KNOW

Compressing a PDF turns its pages into images to make the file smaller, so the text can no longer be selected.
Lower quality settings produce smaller files with less detail.
Conversions use FFmpeg, an open-source library. The full license notices are in Settings.
