How to convert HEIC to JPG, step by step

Ta treść jest po angielsku.

HEIC is the photo format that iPhones have used by default since iOS 11 was released in 2017. It keeps files small, but many websites, email forms, office programs and older computers still expect JPG, so a photo that looks fine on your phone can refuse to upload. This guide explains when converting makes sense, how to use the HEIC to JPG tool on Valtrinity, which quality setting to pick and how to check the result before you delete anything.

What HEIC is and why it causes problems

HEIC is a modern photo format. Its main job is to store a photo in less space than JPG does at a similar visual quality, which is why a phone can keep thousands of pictures without filling up its storage. The downside is compatibility. JPG has been supported almost everywhere for decades, while HEIC support depends on the device, the app and sometimes the version of the operating system.

The usual symptoms are easy to recognise. A form only accepts .jpg or .png files. An email client shows a blank box where the photo should be. A word processor refuses to insert the picture. In each case the photo itself is fine; the program simply does not expect that format.

• HEIC is the default photo format on iPhones since iOS 11 (2017).
• JPG is supported by nearly every website, form and office program.
• Converting HEIC to JPG does not change the photo content, but it does change the file.

When to convert and when to keep HEIC

Convert when you need to send, upload or print a photo and the destination expects JPG. Typical cases include job applications, online forms, school and club websites, insurance claims and shared albums on older computers. Converting is also sensible when you want to put a picture into a document that will be read by other people.

Keep the original HEIC when you are simply storing photos on your phone or in a backup. Converting every photo you own creates a second copy that is usually larger, and it is easy to end up with two versions of everything. A common approach is to keep the HEIC originals and convert only the photos you actually need to share.

• Convert for uploads, forms, email attachments and printing.
• Keep HEIC for archives and phone storage.
• Do not delete the original until you have checked the JPG.

Choose a sensible quality setting

JPG is a lossy format, which means some detail is discarded each time the file is saved. For everyday photos a quality setting between 80 and 90 is a sensible default. Higher values keep a little more detail but the file grows noticeably, while the visible difference on a normal screen is usually small. Going much lower can make skies, skin tones and fine textures look blotchy.

If the photo is going to be printed at a large size, aim for the top of that range. If it is only going on a website or in a chat message, 80 is usually plenty and keeps the upload quick.

• Everyday photos: quality 85.
• Printing or detailed shots: quality 90.
• Quick web or chat use: quality 80.

Step by step: converting one photo

Start by opening the HEIC to JPG tool on Valtrinity. Choose the photo from your device using the upload button. Once the file is loaded, set the quality to a value in the 80 to 90 range. Then start the conversion and wait for the download to appear.

Worked example. Suppose you need to attach a passport-style photo to an online form, and the form rejects the HEIC file. You upload the photo, set quality to 85, convert and download the JPG. Open the new file in your normal photo viewer, check that the orientation and colours look right, and then attach the JPG to the form. Keep the HEIC on your phone in case you need it later.

Converting many photos at once

If you have a folder of fifty holiday photos to send to a relative, convert them in smaller groups rather than all at once. This makes it easier to spot a problem early, such as a wrong orientation or a file that failed to convert. Put the converted files in a new folder so the originals stay where they were.

Rename the converted files if the names matter. Many systems sort files alphabetically, so a simple prefix such as 2026-holiday-01 keeps photos in the order you took them.

• Work in groups of ten or twenty.
• Keep converted files in a separate folder.
• Rename files with a date prefix if order matters.

Check the result before you delete anything

Open each converted file and look at it properly. Check that the picture is the right way up, that colours have not shifted and that the sharpness is acceptable at the size you will use. Some phones also store details such as the date a photo was taken and the location. Not every converter keeps these details, so check them if they matter to you, for example for a claim or an archive.

Only remove the HEIC originals once you are happy with the JPG copies and you have a backup of the originals somewhere else. Deleting the only copy of a photo is the one mistake this process cannot undo.

• Check orientation and colour.
• Check whether date and location details are still there, if they matter.
• Keep a backup of the originals before deleting anything.
