Profile uploads need a square JPG, not a camera original
1 good headshot can still fail when it leaves an iPhone as .heic. Apple made HEIF/HEIC the default with iOS 11 in 2017, and that storage choice still collides with profile forms that accept only JPG or PNG. Start with the flagship HEIC to JPG converter, then resize and compress only when the destination gives a real limit.
HEIC is a compact image container commonly used by iPhone cameras. JPG is a delivery image format that profile sites, resume builders, HR portals, and older CMS tools accept more predictably. LinkedIn's current help page says profile photos must be JPG or PNG and between 400 x 400 px and 7680 x 4320 px in its profile photo upload guidance. Apple documents the iPhone media format in its HEIF and HEVC support guide, while the broader JPEG format remains the safer handoff format for profile images.
Set the crop before conversion cleanup
A profile image is usually shown as a circle, even when the uploaded file is square. Keep enough space around the face so the platform crop does not cut off hair, shoulders, glasses, or a company badge.
Use JPG for normal headshots
Use JPG for ordinary iPhone portraits, office photos, and outdoor headshots. A 90% JPG export is a practical first pass because it keeps skin texture and background edges clean without creating a huge file. If the profile uploader has a 5 MB cap, resize the long edge to 1200 px or 1600 px with the image resizer before dropping quality below 82%.
Use PNG only for graphic-heavy profile images
Use PNG when the image includes a logo frame, text overlay, flat-color background, or sharp graphic border. PNG can be 2x to 5x larger than JPG, so it is not the default for a camera portrait.

How browser-local profile photo conversion works
Browser-local conversion reads the selected HEIC through the browser File API, decodes the HEIF container and HEVC-compressed image data with native support or a WebAssembly codec such as libheif, draws the decoded pixels into a Canvas-style bitmap, and exports a JPEG blob at the selected quality. That mechanism matters because conversion fixes the rejected .heic extension, resizing fixes square or oversized dimensions, compression fixes caps such as 2 MB, 5 MB, or 10 MB, and EXIF cleanup fixes hidden capture data. Treat those as separate operations instead of repeatedly saving the same photo until the upload passes.
A clean profile-photo workflow
Keep one untouched original and one delivery copy. That gives you a reset point if the crop, file size, or site compression looks wrong.
- Save the original HEIC in Photos, Files, or your archive folder.
- Crop to a square first, keeping the face centered with extra margin for circular previews.
- Convert through / at about
90%JPG quality. - Resize to
1200 x 1200 pxor1600 x 1600 pxwhen the original came from a 12 MP or 48 MP iPhone camera. - Run the JPG through the image compressor only if the upload form rejects the file size.
- Remove metadata with the EXIF remover before using a photo taken at home, school, a clinic, or a private workplace.
For multiple versions, use the batch converter after choosing the final crop style. If you are comparing local conversion with remote tools, the privacy tradeoff is covered in Browser-Local HEIC Converter vs Cloud Uploads, and the practical cloud-tool comparison is in free alternative to CloudConvert.
Windows support can still be misleading. A Windows 11 23H2 PC on build 22631 may preview HEIC after codec support is installed, while a profile uploader rejects the same file because it checks only .jpg and .png. Preview support is not the same as upload support.
FAQ
Can LinkedIn upload an iPhone HEIC profile photo?
LinkedIn's help page lists JPG and PNG for profile photos, so convert the iPhone HEIC to JPG before uploading. Aim for a square image at least 400 x 400 px, with a larger 1200 x 1200 px copy if you want more crop flexibility.
What JPG quality should I use for a profile photo?
Start at 90% quality. If the file is still too large, resize the square image before lowering quality, because a clean 1200 px JPG usually looks better than an over-compressed full-resolution export.
Should I remove EXIF from a profile picture?
Yes when the image will be public. EXIF can include capture time, device model, and sometimes GPS location, while a profile page needs only the visible headshot.
Is PNG better than JPG for profile photos?
JPG is better for normal camera portraits because it keeps file size manageable. PNG is better when the profile image includes text, a logo frame, or flat graphics where JPEG artifacts would show.
Bottom line
Profile sites need a compatible delivery image, not the untouched camera original. Keep the HEIC as your archive, create one square JPG copy, resize before heavy compression, and strip metadata before posting the image publicly.
