Does converting HEIC to JPG reduce photo quality?

Yes, but only slightly at high quality settings. Both formats are lossy, so converting means encoding twice. At 92% quality the visual difference is negligible for photos viewed on screen or printed at standard sizes. If you plan to edit after converting, export from the original HEIC at the highest quality setting and avoid re-saving a converted JPG multiple times.

Is there a file size limit for HEIC conversion?

The tool handles files up to 50MB each and batches of up to 20 files at once. Very large HEIC files from iPhone Pro cameras, especially 48MP ProRAW shots saved as HEIC, can approach or exceed this limit.

Is the QuickBrew HEIC to JPG converter free?

Yes, completely free. No account required, no watermarks, no paid tier for higher limits. QuickBrew is ad-supported and all tools are free to use.

Why can't I just rename a HEIC file to JPG?

File format is determined by the data structure, not the file extension. Renaming a HEIC to JPG does not convert it. Most software will fail to open it or display incorrect output. Actual conversion decodes the HEVC-compressed data and re-encodes it as JPEG.

What happens to burst photos or Live Photos when converting HEIC?

The converter extracts the primary still image from each HEIC or HEIF file. Burst sequences produce one JPG per file using the primary frame. Apple Live Photo motion data does not carry over to JPG format.

How to Convert HEIC Photos to JPG Without Installing Anything

Convert HEIC to JPG now

Your iPhone shoots in HEIC by default, and Windows doesn't open it natively. Neither does most of the web. You're here because you have photos you can't share, post, or edit without jumping through hoops first.

QuickBrew's HEIC to JPG converter runs entirely in your browser using WebAssembly. Nothing gets uploaded anywhere.

When You'd Need This

The most common situation: you took photos on your iPhone and need to send them to someone on Windows, post them to a website, or submit them through a form that only accepts JPG or PNG. HEIC is Apple's format and it stays Apple's format until you convert it. Windows 10 and 11 can open HEIC files if you pay Microsoft for the HEVC Video Extensions codec (yes, really), but that's not a solution you can hand to someone else.

Creative workflows hit this wall too. Lightroom Classic handles HEIC fine, but many older versions of Photoshop, web-based editors, and third-party tools don't. If you're sending proofs to a client, submitting photos to a print lab, or uploading product shots to an e-commerce platform, JPG is the safe choice every time.

The other scenario is archiving or sharing over platforms that strip metadata or recompress anyway. Instagram, most CMS platforms, and email attachments all do fine with JPG. Converting upfront means you control the quality settings rather than letting the platform decide.

How to Convert HEIC to JPG

Go to quickbrew.tools/tools/heic-to-jpg/
Drop your HEIC or HEIF files onto the upload zone, or tap it to browse on mobile.
Choose your output quality if the default (92%) isn't what you need.
Click Convert, then download your JPG files individually or as a ZIP.

That's it. No account, no email, no waiting for a server. The conversion runs locally in your browser.

What's Actually Happening

HEIC uses HEVC (H.265) compression, the same codec that compresses 4K video efficiently. Apple adopted it in iOS 11 because it produces roughly 40–50% smaller files than JPG at comparable visual quality. A photo that would be 4MB as a JPG often comes in around 2–2.5MB as HEIC. The tradeoff is compatibility: HEVC decoding requires hardware or software support that isn't universal.

When you convert HEIC to JPG, the process decodes the HEVC-compressed image data into raw pixel values, then re-encodes it using JPEG's DCT compression. There's no magic here: JPG is a lossy format, and re-encoding introduces a small amount of additional degradation. At 92% quality (the default), the difference is not visible to the naked eye. At 80%, the file gets smaller but smooth gradients and fine detail start to show compression artifacts on close inspection.

File size math works roughly like this: a 3MB HEIC from an iPhone 15 converts to about 4–5MB JPG at 92% quality, or around 2MB at 80% quality. HDR shots tend to run larger because of the wider tonal range being mapped down. Portrait mode photos with depth data will lose the depth map entirely during conversion, since JPG has no way to store it.

Color space is worth knowing about if you care about accuracy. iPhone cameras shoot in Display P3, a wider color gamut than standard sRGB. Most HEIC-to-JPG converters (including this one) convert to sRGB on output, which is correct for web use. Highly saturated colors in Display P3 that fall outside sRGB will get clipped or shifted slightly.

Your Photos Contain More Than Pixels

iPhone photos embed GPS coordinates, the time and date, device model, and in some cases face recognition data in the EXIF metadata. QuickBrew preserves or strips this metadata based on the option you choose before downloading. If you're sharing photos publicly or sending them to people you don't know, it's worth stripping the GPS tags. The conversion runs locally, so no one at QuickBrew ever sees your metadata (or your photos).

Beyond GPS, HEIC files can embed depth maps from Portrait mode and HDR gain maps. These don't carry over to JPG. What you get is the primary image, flattened and re-encoded.
