You took the photos on your iPhone: a product shot, a signed form, an ID card for a college application, a picture of a damaged parcel for a refund claim. Then you try to upload it and the website says "file type not supported". Or you email it to someone on Windows and they reply that it will not open.

The problem is usually the file format. Recent iPhones save photos as HEIC (sometimes shown as HEIF) by default. It is a perfectly good format, but plenty of upload forms, government and college portals, marketplaces and older Windows apps still expect JPG. This guide shows how to convert HEIC to JPG quickly, which settings to pick, and the mistakes that cause rejected uploads. It is written for small business owners, students and sellers who just need the photo to work.

What HEIC is, in one paragraph

HEIC is the file type iPhones and iPads use when the camera is set to "High Efficiency". It keeps photos small on the phone while looking good. The catch is compatibility: JPG has been around for decades and opens almost everywhere, while HEIC support depends on the app, the browser and the operating system. When a form or a person cannot open your photo, converting it to JPG is the simplest fix.

Step-by-step: convert HEIC to JPG

You can use the free HEIC to JPG converter from PKD Ventures. Here is the routine:

  1. Get the original files onto your computer or open the tool on your phone. If you AirDrop, email or copy photos to a laptop, check that the files end in .heic or .heif. Those are the ones that need converting.
  2. Add your photos. You can add one photo or a batch of up to 20 at once. Each file can be up to 25 MB.
  3. Choose the JPG quality. There is a quality slider from 50% to 100%, and it starts at 92%. For most uses, leave it there (see the tips below for when to change it).
  4. Click "Convert to JPG". On browsers without built-in HEIC support, the tool first downloads a decoder of about 2.7 MB. That happens once, so the first conversion can take a little longer.
  5. Download the results. Save each JPG on its own, or download the whole batch as a single ZIP file, which is handy when you have converted a dozen product photos.
  6. Open one JPG before you upload it. A quick look confirms the photo is the right one, the right way up and readable.

That is it. The JPG files can now go into the portal, the marketplace listing, the email or the WhatsApp Business catalogue.

Picking the right quality setting

The quality slider controls how much detail JPG keeps and how big the file is. Higher quality means a larger file.

  • 92% (the default): a good balance for almost everything: product photos, sharing with clients and printing small prints.
  • 95–100%: use when you will edit the photo further, or print it large. Expect noticeably bigger files.
  • 70–85%: use when a portal has a strict size limit (forms that cap uploads at a few hundred KB are common) or when you are sending many photos over a slow connection.
  • Below 70%: only when the size limit is very tight. Look closely at text and edges, because blocky "JPG artefacts" start to show.

If you still cannot get under a size limit, convert at the default quality first, then shrink the JPG with an image compressor. Reducing the pixel dimensions usually saves far more space than dropping quality to a very low number.

Privacy bonus: location data is not copied

iPhone photos often carry hidden details called EXIF metadata, which can include where the photo was taken and which phone took it. This converter does not copy EXIF metadata into the JPG. For most sharing, that is a good thing: you can send a photo of your shop counter or home office to a stranger without also sending its location.

The flip side: if you need the date or location stored in the file (for example, for a photo archive or certain insurance claims), keep your original HEIC files as well, and do not delete them after converting.

Tips for common situations

Sellers listing products. Convert the whole batch at once, download the ZIP, then rename files to something clear like cotton-kurta-blue-front.jpg before uploading. Clear names make your own catalogue easier to manage.

Students uploading documents. Many college and exam portals want a JPG of a photo, signature or certificate, with a size limit. Convert to JPG, then crop and compress to meet the exact rules. If the portal asks for a PDF instead, you can turn the JPGs into one file with JPG to PDF.

Business owners sharing with a team on Windows. Rather than converting photo by photo, convert in batches of up to 20 and share the ZIP.

Photos with transparent areas. Standard iPhone camera photos are not transparent, but if a HEIC file does contain transparency, JPG cannot store it. Those areas become a solid colour (white) in the JPG.

Common mistakes to avoid

  • Renaming .heic to .jpg. Changing the file extension does not change the file. The photo is still HEIC inside, and many websites will reject it or show a broken image. Always convert.
  • Converting screenshots that are already PNG or JPG. iPhone screenshots are usually PNG, not HEIC. If a file already ends in .png or .jpg, this tool is not the one you need.
  • Expecting Live Photos to come out as video. Only the main still image is converted. The moving part of a Live Photo is a separate video file and is not included.
  • Multi-image HEIC files. Some HEIC files hold more than one image (for example, burst or depth photos). Only the main image is converted, and some unusual variants cannot be decoded at all. If you see a "could not be decoded" message, try exporting the photo again from the Photos app.
  • Setting quality to 100% "to be safe". It rarely looks different on screen and can make files much larger, which is exactly what upload limits reject.
  • Deleting the originals. Keep the HEIC files until you are sure the JPGs are right, especially if you need the metadata.
  • Very large photos on an old phone. They can be slow to convert. If your phone struggles, convert on a laptop or do fewer photos at a time.

How to stop the problem at the source (optional)

If you constantly need JPGs, you can change the iPhone itself. In Settings > Camera > Formats, choosing "Most Compatible" makes the camera save new photos as JPG instead of HEIC. It only affects new photos, and the files take more space on the phone, so many people keep "High Efficiency" and convert only when a site or person needs JPG.

There is also a setting under Settings > Photos > Transfer to Mac or PC. With "Automatic" selected, the iPhone converts photos to a compatible format when you copy them to a computer over a cable. It does not help with every sharing route, which is why a converter is still useful.

Quick checklist before you upload

  • The file ends in .jpg, not .heic.
  • You opened the JPG and it is the right photo, the right way up.
  • The file size is under the portal's limit (compress or resize if not).
  • You kept the HEIC originals if you need the location or date data.

Wrapping up

HEIC is a good format on the phone, but JPG is still what most websites, portals and people can open. Convert with HEIC to JPG, keep quality around the default, compress only if a size limit demands it, and check one file before you upload.
