The Ultimate File Converter & Compressor for iPhone

The iPhone app converts images (HEIC, WEBP, PNG, JPG, RAW and more) to JPG, PNG, HEIC, WEBP, PDF, GIF, TIFF or BMP; video to MP4, MOV, M4V, MKV, AVI or GIF; the sound of a video or an audio file to MP3, M4A, WAV, AAC, FLAC or AIFF; and Word, RTF, TXT, Markdown and HTML files to PDF. It also merges, splits and compresses PDFs, saves PDF pages as JPG or PNG, compresses video, photos and audio, and creates or extracts ZIP archives. It does not convert PDFs to Word, Excel or PowerPoint, and it does not open RAR, 7z or password-protected ZIP files.

In the app, tap Images, choose up to 50 photos, pick JPG as the output format and convert; the conversion runs on your iPhone. For a quick one-off, the free HEIC to JPG and PNG to JPG tools on this site work in Safari without installing anything.

Yes. The app converts video to MP4, MOV, M4V, MKV, AVI or GIF, including MOV to MP4, MP4 to MKV and AVI to MP4, and also opens WebM, WMV, FLV, MPG and 3GP files. It can save a video's sound as MP3 too. Video is converted on your iPhone, not uploaded.

DOCX to PDF, yes: the app turns Word (DOCX, DOC), RTF, TXT, Markdown and HTML files into PDF on your iPhone, without uploading them. PDF to Word, no: the app does not convert PDFs into Word, Excel or PowerPoint files. It can merge, split, reorder, rotate, number, password-protect and compress PDFs and turn photos into a PDF; the free Merge PDF, Split PDF and JPG to PDF tools on this site also do that in your browser.

Yes. The app compresses video, photos, PDFs and audio on your iPhone, and for videos it shows the estimated size before you start. To shrink a few photos without installing anything, use the free Compress Image tool on this site.

The app is free to download and has no ads. Converting, compressing and previewing are free; saving or sharing the results requires File Converter Pro, a subscription (weekly with a 3-day free trial for eligible new subscribers, or yearly). Every conversion runs on your iPhone and works offline, so your files are never uploaded. The free browser tools on this site also run entirely in your browser.

Yes. All 18 browser tool pages (an image converter, HEIC to JPG, PNG to JPG, JPG to PNG, WEBP to JPG, two image compressors, JPG to PDF, Merge PDF, Split PDF, PDF to JPG, and MP4, MOV, video, M4A, Voice Memo, WAV and audio to MP3) are free, with no sign-up and no watermark. Your files are processed by the browser on your own device and are not uploaded.
