Contact

For help with Convert (照片转换, project name FileSubmit), email onefish857@gmail.com. Include your iOS version, app version, selected output format and a description of the issue. Please do not send private original photos or documents.

Convert and save

Choose 1–10 HEIC, JPG or PNG images from Photos or Files. Select JPG, PNG or a combined PDF and set pixel dimensions as needed. JPG and PDF also support an optional file size cap; PNG does not use a size cap or lossy quality compression. Then convert. Preview the results before saving or sharing. Save JPG and PNG copies to Photos or Files; save PDFs to Files. Your originals stay unchanged.

A size limit cannot be met

Pixel dimensions and file size are separate requirements. If the selected size limit cannot be met, the result asks you to choose what to keep: keep the dimensions and relax the size limit, or explicitly choose smaller dimensions. The app does not silently reduce your selected dimensions. Check the website's exact rules and preview small text before uploading.

Start from Photos

Select up to ten photos, tap Share and choose Convert in the app row. If it is missing, swipe to More at the end of that row and add it to Favorites. Video-only selections and more than ten images are not supported.

Use a shortcut

Open Tips in Convert and tap Add Shortcut. Confirm in Apple's Shortcuts app. The shortcut selects one image, converts it to JPG at the original pixel dimensions, and previews a copy. No file size cap is applied. Use the preview's Share button to save or send it.

Originals in iCloud and saving permission

iCloud originals may need to download before conversion. When saving to Photos, allow Add Photos permission if prompted. You can also save images or PDFs to Files or share them through the system share sheet. Working files are temporary, so save copies you want to keep.

Price and privacy

All version 1.0 features are free, with no subscriptions, in-app purchases, ads or user accounts. Conversion runs on your device; the app does not upload photos. These product support and legal pages do not include analytics scripts. See the linked Privacy Policy and Terms of Use for details.
