HEIC to JPG Quality Settings Explained: What % to Pick

You converted a 2 MB HEIC photo and got back a 6 MB JPG. Or you’re wondering whether to pick 80% or 100% quality. HEIC-to-JPG quality settings confuse everyone — this guide explains exactly what the quality slider does, when it matters, and what to pick for every common situation.

Why Is My Converted JPG Bigger Than the HEIC?

This surprises everyone, so let’s get it out of the way: it’s normal and expected.

HEIC uses dramatically more efficient compression than JPG — roughly twice as efficient. The same photo at visually identical quality takes about half the space as HEIC compared to JPG. When you convert HEIC → JPG, you’re moving from a modern format to a 30-year-old one. The JPG has to be bigger to hold the same visual detail.

Typical sizes for the same iPhone photo:

HEIC: 1.5–2.5 MB
JPG at 90% quality: 3–5 MB
JPG at 80% quality: 2–3.5 MB
JPG at 100% quality: 6–10 MB

If file size matters more than squeezing out the last 2% of quality, 80–85% is the sweet spot.

What Does the Quality Percentage Actually Mean?

The quality slider (usually 1–100%) controls how aggressively the JPG compressor discards image data:

100%: minimal compression. Huge files, virtually indistinguishable from the original. Only useful for archival or professional print work.
90–95%: excellent quality. Files still large, but this is the “can’t tell the difference” range for most people.
80–85%: the sweet spot. Visually identical to 95% in normal viewing, but 30–40% smaller files. This is what most people should pick.
70–75%: good for web thumbnails and social media. Slight artifacts visible on close inspection, fine at normal viewing distance.
Below 60%: noticeable blockiness and color banding. Only for tiny previews where size matters more than anything.

What Quality Should You Pick? (By Use Case)

You’re converting for…	Pick	Why
Printing photos	95–100%	Print reveals compression artifacts that screens hide
Uploading to a website / blog	80–85%	Best balance; visitors can’t tell the difference
Social media	75–85%	Platforms recompress anyway — don’t waste bytes
Email attachments	80%	Good quality, reasonable size
Archiving / backup	100%, or keep the HEIC	If quality matters long-term, don’t throw data away

Does Converting HEIC to JPG Lose Quality?

Technically yes, practically no — if you pick the right setting.

HEIC → JPG is a lossy-to-lossy conversion. You’re decompressing the HEIC to a full image, then recompressing as JPG. At 85%+ quality, the generational loss is invisible to the human eye. At 70% or below, you may notice softening in detailed areas (foliage, fabric texture, distant text).

The one thing you can’t get back: HEIC’s 10-bit color depth. JPG is 8-bit. In practice this only matters for extreme editing (heavy shadow recovery, dramatic color grading). For viewing and sharing, it’s irrelevant.

What About Live Photos? Do You Lose the Video?

Yes — converting a Live Photo to JPG keeps only the still frame. The 3-second video clip is discarded.

If you want to preserve the motion:

On iPhone: share as a video instead (the Live Photo can export as a .mov).
Convert to GIF or MP4 if you want the animation in a shareable format.
Our HEIC to JPG converter handles the still extraction; for the video part, use your phone’s share sheet.

Do Converters Keep Your Photo’s Metadata (EXIF / Location)?

This is a real privacy consideration most guides ignore.

EXIF data (camera settings, date taken) is usually preserved by desktop converters but often stripped by online converters.
GPS location embedded in iPhone photos is the sensitive one. Some online tools strip it; some don’t. If privacy matters, check the tool’s policy or strip EXIF yourself before uploading.
Our HEIC to JPG tool strips all EXIF automatically — conversion happens entirely in your browser: the photo is decoded to raw pixels, drawn to a canvas, and re-encoded as a fresh JPG. No metadata survives the trip (camera settings, date taken, GPS location), and your file never leaves your device.

Batch Converting HEIC to JPG

Got hundreds of iPhone photos to convert? You have options:

Our online tool (HEIC to JPG) — quick for batches of up to 10–20 at a time, no install.
Mac: select photos in Finder → right-click → Quick Actions → Convert Image. Built in, handles batches.
Windows: install the HEIF Image Extensions from the Microsoft Store, then use any batch image tool.
Power users: sips -s format jpeg *.HEIC --out converted/ (Mac terminal) converts entire folders.

Why is HEIC smaller than JPG?

HEIC uses HEVC/H.265 video compression techniques adapted for still images — roughly twice as efficient as JPG’s 1990s-era DCT compression. Same visual quality, half the bytes.

Should I convert HEIC to JPG or PNG?

JPG for photos (smaller files, quality is fine). PNG only if you need lossless quality or transparency — but note that HEIC photos don’t have transparency, so PNG just gives you a much bigger file for no benefit. For most photos: HEIC to JPG at 85%.

Can I convert HEIC to JPG without losing quality?

Not zero loss (it’s lossy-to-lossy), but at 90%+ quality the loss is imperceptible. If you need mathematically lossless, convert to PNG or TIFF instead — but expect very large files.

Does iPhone let you shoot in JPG instead of HEIC?

Yes: Settings → Camera → Formats → “Most Compatible.” Your photos will save as JPG going forward (at the cost of ~2x storage per photo).

Why can’t Windows open my HEIC files?

Windows doesn’t include HEIC support by default. Install “HEIF Image Extensions” from the Microsoft Store (free), or just convert to JPG online — faster for one-off files.
