Every result is saved to the My Creation tab, where you can preview, rename, share, save to Files or Photos, or delete it. The same folder is also visible in the iOS Files app under On My iPhone → Evir → My Creations.

Video: MP4, MOV, MKV, WEBM, AVI, M4V, TS, 3GP, FLV, WMV, MPEG, OGV, and more — with codecs including H.264, HEVC, VP8/VP9, AV1, and ProRes.

Audio: MP3, M4A, AAC, FLAC, WAV, AIFF, OGG, OPUS, AC3, AMR, and more.

Image: JPG, PNG, HEIC, WEBP, TIFF, and BMP, plus Image → PDF and Video → GIF.

PDF: scan, compress, merge, split, export pages as images, and password-protect.

The exact codec list adapts to what the chosen container supports.

When you only change the container (for example MKV → MP4) and keep the codec, Evir can remux: it repackages the streams without re-encoding them. This is enormously faster — often 100× — and completely lossless. If you change resolution, bitrate, codec, or other picture settings, a re-encode is required, and Evir uses hardware (GPU) acceleration for H.264 and HEVC when possible.

Use Video → Compress. Pick a resolution preset (1080p or 720p usually gives big savings), or lower the bitrate. The screen shows the original size next to the estimated output size, so you can see the savings before you start. HEVC (H.265) generally produces much smaller files than H.264 at the same quality.

Use Audio → Ringtone to export a clip of up to 30 seconds as an M4R file, then follow the in-app guide: share the file to the GarageBand app or use the share sheet's "Use as Ringtone" flow, and it appears in Settings → Sounds & Haptics.

Yes — start a job and go back for another; conversions queue up in the job list, where you can watch progress and cancel individual jobs. Keep Evir in the foreground while jobs run: iOS pauses heavy processing when an app goes to the background.

You may have granted access to only some items. Open iOS Settings → Privacy & Security → Photos → Evir and choose Full Access, or tap the selection banner in the app to add more items. You can also pick the file through Files instead — that needs no photo permission at all.

No. All processing runs on your device — Evir even works in Airplane Mode. The only network requests the app ever makes are version checks for updates. See the Privacy Policy for details.

Ask it what Evir can do — for example "how do I make a GIF?" — and it points you at the right tool. On devices with Apple Intelligence (iOS 26 and later), it uses Apple's on-device model; on other devices it uses built-in answers. It never accesses your files.

• Make sure your device has enough free storage — video work needs temporary space.
• Try a different output format or codec; a few exotic combinations aren't supported.
• For very large files, try the "Without re-encoding" option if it's offered.
• Still stuck? Email us — include the source format and the settings you chose.
