> What to look for in an iPhone file converter app, and how Filevale converts PDF, HEIC, video, audio, ZIP and RAR on-device, free with no account.

Search the App Store for "file converter" and you get dozens of apps that look alike. Many of them send your file to a server to convert it, lock basic features behind a weekly subscription, or show a paywall before the first conversion. Adobe Acrobat is excellent for PDFs, but it does not convert video, audio or archives.

Here is what to check before you install one, and why Filevale is a good fit if you want one app for most file jobs.

## What makes a good iPhone file converter

- **On-device conversion.** The file should be converted on your iPhone, not uploaded. That is faster on modern iPhones and keeps private documents private.
- **Share sheet support.** You should be able to send a file from Files, Mail, WhatsApp or Photos straight into the app.
- **Many formats in one app.** PDF, photos, video, audio and archives, so you do not need five apps.
- **Clear pricing.** You should be able to try the conversion you need before paying for anything.

- **Video and audio**: a video compressor for WhatsApp or email, and MP3 from audio and video.
- **Archives**: open ZIP, RAR and 7Z files.
- **QR codes**: make QR codes on-device.

A Mac app is coming soon.

Filevale for Mac is in App Review and coming soon to the Mac App Store. Until then, use the free web tools above on your Mac, or the [Filevale iPhone app](https://filevale.com/go/ios?src=guide-md).

## No app? Use the browser

Most of these tools also exist on filevale.com and work in Safari on iPhone, again without uploading your file. Text recognition for scans is only in the app. That is handy on a borrowed phone or when you only need one conversion.

[Open HEIC to JPG Converter](https://filevale.com/heic-to-jpg/)

- [HEIC to JPG](/heic-to-jpg/) for iPhone photos that won't open on Windows.
- [Compress Video](/compress-video/) when a clip is too big to send.
- [Scan to PDF](/scan-to-pdf/) to photograph paper documents into one PDF.
- [Extract Archive](/extract-archive/) for ZIP, RAR and 7Z attachments.

In the browser, heavy jobs such as a long 4K video are slower than in the app, so the app is the better choice if you convert often.

## Frequently asked questions

Yes. Open filevale.com in Safari, choose a tool such as HEIC to JPG or Compress Video, and add your file from Photos or Files. The conversion runs in the browser.
