How to convert HEIC photos to JPG

Why iPhones use HEIC

HEIC can store high-quality photos more efficiently than older formats. The disadvantage is compatibility: some websites, forms and older applications still accept JPG but not HEIC.

Convert a local copy

Choose the HEIC photo, select JPG as the output, review the quality setting and download the converted copy. MyFileNest performs the supported conversion in your browser, so the photo is not uploaded to a conversion server.

Quality and metadata

JPG is a lossy format. A sensible high-quality setting preserves normal viewing quality, but conversion cannot retain every HEIC feature. Keep the original HEIC file as your archival copy.

If location or camera metadata matters, inspect the downloaded file before deleting the original. Some browser conversion workflows intentionally omit metadata for privacy.

When PNG is a better result

Choose PNG when lossless editing matters more than file size. For ordinary photographs and upload forms, JPG is usually smaller and more widely accepted.

Worked decision: a photo rejected by an application form

Check the form's accepted extension, maximum size and required dimensions before converting. Convert one local HEIC photo to JPG, open the result and confirm its orientation. If the JPG is still too large, resize a copy to the form's required dimensions before reducing quality further. Renaming a .heic file to .jpg does not convert its contents.

Inspect faces and fine lettering at the intended viewing size. Keep the original HEIC separately because the JPG is a delivery copy: conversion may not preserve depth data, image sequences, HDR behavior or the original metadata. If color looks different, compare in the same viewer before deciding whether it is a conversion issue.

When conversion fails

Try a single photo rather than a large batch to distinguish a memory problem from an unsupported file. If the same file still fails, export a JPG using the device's photo application and compare that result. A HEIC container can hold features that a browser decoder does not support; another retry is not a guarantee that it will work.

Where HEIC files cause problems

HEIC support has improved, but gaps remain in exactly the places people tend to need photos most.

Step-by-step: converting a batch from an iPhone

1. On the iPhone, open this page in Safari and tap the file picker, or transfer the photos to your computer first.
2. Choose up to 20 HEIC photos. Large batches are easier to manage in groups.
3. Pick a JPG quality. Around 90% suits keepsakes and printing; 75–85% suits uploads and messaging.
4. Convert and download. Several photos arrive together in a ZIP file.
5. Open two or three converted photos and check orientation, colour and sharpness.
6. Upload or share the JPG copies and keep the HEIC originals in your photo library.

Choosing between converting and changing camera settings

If you only occasionally need JPG, converting when needed is the better choice. HEIC saves storage on your phone, typically around half the space of an equivalent JPG, and the photo library keeps the richer original.

If you constantly upload photos to systems that reject HEIC, switching the camera to Most Compatible in Settings, Camera, Formats saves time. New photos will be JPG, at the cost of more storage use. A middle path is Settings, Photos, Transfer to Mac or PC, Automatic, which keeps HEIC on the phone but gives compatible files when you copy them to a computer by cable.

Worked example: a rental application

A tenant must upload photos of their payslips and ID to a letting agent's portal that lists JPG, PNG and PDF as accepted types. Their iPhone photos are HEIC and do not appear in the portal's file picker on their laptop. Converting the four photos to JPG at 85% gives files of about 1–2 MB each, well inside the portal's 10 MB limit. Because the documents are sensitive, converting them in the browser rather than on an upload-based converter means the payslips are not stored on another company's server.

If the agent had asked for one document rather than separate photos, HEIC to PDF would have produced a single PDF directly from the same HEIC photos.

Troubleshooting

• The converted photo is sideways: open it in another viewer; if it is still sideways, rotate it with Rotate Image. Some workflows rely on an orientation tag that may not carry across.
• The browser runs out of memory: convert fewer photos at a time, close other tabs, or use a computer instead of an older phone.
• A file will not convert: some HEIC files contain features that browser decoders do not support. Export that photo as JPG from the Photos app instead.
• Colours look duller: wide-colour photos may be mapped to standard colour in JPG. The change is usually subtle and only visible side by side.

HEIC, HEIF and HEVC explained

The names are easy to mix up. HEIF, the High Efficiency Image File Format, is the container standard: it defines how one or more images and their metadata are stored in a file. HEVC, also known as H.265, is the compression method used for the image data inside. HEIC is the file extension Apple uses for HEIF files that contain HEVC-compressed images. In everyday use, HEIC and HEIF files from phones are treated the same way.

Because HEVC is a modern compression method, it stores a photo in roughly half the space of a comparable JPG. It also supports features JPG does not, such as multiple images in one file, depth information for portrait effects and higher colour depth. Those features are a big part of why conversion to JPG keeps only the main still image.

Batch workflows for large photo libraries

Converting a few photos is quick; converting hundreds needs a plan. Work in batches of up to 20 photos, grouped by event or date, so each ZIP is easy to name and file. Name the ZIPs descriptively, for example 2026-07-holiday-jpg.zip, and extract them into folders that mirror the original organisation.

Before converting a whole library, convert one batch and check orientation, colours and file sizes. If they are fine, keep the same quality setting for the rest so the library is consistent. Keep the original HEIC files until you are sure every converted batch opened correctly; a backup drive or cloud photo library is the right place for the originals.

If you regularly receive HEIC files from family or colleagues, it may be easier to ask them to change their sharing settings, or to export as JPG from their Photos app, than to convert every file you receive.

Converting on Windows, Mac and Android

On a Mac, Preview and the Photos app can export HEIC as JPG directly. On Windows, the Photos app can open HEIC files if the HEIF Image Extension and, for some versions, the HEVC Video Extension are installed, after which you can save a copy as JPG. Android phones increasingly support HEIF too, but older devices and many apps do not.

A browser-based converter works the same way on all of these systems without installing anything, which is useful on work computers where you cannot add software, or when you need to convert someone else's photos quickly.

Choosing between JPG, PNG and PDF output

JPG is the right choice for nearly all photo sharing: it is compact and universally supported. PNG is useful when you will edit the photo further and want to avoid another round of lossy compression, or when an application requires PNG; expect much larger files. PDF is best when several photos together form a document, such as pages of a form, a set of receipts or a multi-page letter photographed with a phone.

If in doubt, convert to JPG at a high quality. You can always create a PDF from the JPGs later with JPG to PDF, while going from PDF back to individual photos is more work.

Privacy

Phone photos are personal: they show homes, children, documents and places you visit regularly. MyFileNest converts HEIC files in your browser, so the photos are not uploaded to a conversion server. Location and camera details may not be carried into the converted JPG, which reduces what you share by accident. Still review each picture before posting it publicly, and delete converted copies you no longer need from shared folders.

Summary

HEIC saves space on iPhones but is still rejected by many forms, older computers and websites. Convert copies to JPG when you need compatibility, in batches of up to 20, at a quality that suits the destination, and keep the HEIC originals in your photo library. If you constantly need JPG, change the iPhone's camera format or transfer settings instead.
