Short answer: Copy iPhone HEIC to your PC (USB, iCloud, or Google Photos export), open HEIC to JPG in Chrome or Edge, drop files in batches of 40–60 on 8 GB RAM (150+ on 16 GB desktop), set JPEG quality to 85–90%, convert, download a ZIP. Nothing uploads to our servers.
We wrote this after converting real vacation folders while testing HeicSave—not a generic “five easy steps” list. You will see where files land, sensible batch sizes, and what to expect for file sizes after export.
Scenario: 187 photos from a two-week trip
iPhone 15 Pro, 48 MP HEIC stills, 187 files after deleting duplicates. Folder on disk: about 620 MB. Goal: JPGs for Google Photos backup, email to family, and a Premiere slideshow.
That mix is why batch matters—you are moving a whole camera roll off Apple’s format before anyone else can open it.
Step 1 — Get HEIC files onto your computer
| Source | What you get | Gotcha |
|---|---|---|
| USB cable → copy DCIM folder | Fast; full resolution | Windows may show generic icons until converted |
| iCloud for Windows → Downloads | Convenient sync | Still HEIC unless iPhone set to Most Compatible |
| AirDrop to Mac → copy to PC | Easy on Apple hardware | Large folders need batch on Mac too |
| Google Photos → Download album | Works cross-platform | Google may deliver HEIC or JPG depending on settings |
If Windows Explorer will not preview thumbnails, that is normal without HEIF extensions. You can still convert—see our HEIC on Windows guide.
Live Photos: each shot may include a .heic still and a .mov video. Convert the .heic files only. Skip .mov unless you know you need video.
Step 2 — Open the converter and set quality first
- On the PC, open Chrome or Edge (best HEIC decode on Windows).
- Go to HEIC to JPG.
- Move the quality slider to 85–90% before adding files. Default 90% is fine for family sharing and print up to 8×10. Drop to 80% only if email size limits bite.
Why set quality first? Every file in the batch uses the same setting. Mixing re-runs wastes time.
Step 3 — Batch size: match your RAM
HeicSave has no fixed file-count cap. Your limit is browser memory decoding full-resolution HEIC.
| PC RAM | Suggested batch | Notes |
|---|---|---|
| 8 GB laptop | 40–60 HEIC files | Close Slack, Teams, extra tabs |
| 16 GB desktop | 120–200 HEIC files | ZIP download after each batch |
| 8 GB + 48 MP RAW-like exports | 20–30 files | Split aggressively |
Workflow loop: drag batch → Convert → Download ZIP → rename ZIP (e.g. trip-batch-01.zip) → refresh page if tab feels slow → next batch.
On a 16 GB Windows 11 laptop with Chrome, converting 100 HEIC files (12 MP mix) often finishes in under three minutes—local decode, no upload wait.
Step 4 — File sizes after conversion
HEIC is already compressed. JPG adds a second lossy generation. Expect:
- 12 MP HEIC ~1.2–2.5 MB → JPG at 90% often 1.5–3.5 MB
- 48 MP HEIC ~2–5 MB → JPG at 90% often 4–8 MB
A 620 MB HEIC folder might become ~900 MB–1.1 GB JPG at high quality. That is normal. For email, run a second pass at 80% or resize in the tool if we add presets later—for now, split attachments.
Need lossless raster for design? Use HEIC to PNG for hero images only; JPG for the bulk.
Step 5 — Verify EXIF and orientation
HeicSave copies common EXIF fields when the browser allows: capture date, camera model, orientation. GPS may drop depending on browser privacy rules.
After unzipping, spot-check three files:
- Photos app — correct date ordering?
- File Explorer Details — dimensions match iPhone?
- One portrait shot — orientation not sideways?
Keep the original HEIC folder as archive until you confirm JPGs look right.
Why local batch beats cloud upload converters
Cloud tools queue your files on their servers. For 187 photos at ~3 MB average (~560 MB upload), a 10 Mbps home upload needs ~12+ minutes before conversion even starts—plus privacy terms you may not read.
HeicSave decodes with WebAssembly in your tab. On the same machine, batch decode often beats upload+queue for folders over 30 files, and you avoid sending medical, legal, or family images to a third party.

Troubleshooting batch runs
| Symptom | Fix |
|---|---|
| Tab freezes mid-batch | Fewer files; refresh; use desktop not phone browser |
| “Unsupported file” | Confirm extension is .heic/.heif, not renamed .jpg |
| Colors look washed out | See HEIC color washed out after convert |
| Outlook still rejects JPG | Attachment may exceed 20–25 MB—split ZIP or lower quality |
| Premiere import slow | Convert first anyway—see HEIC in Premiere Pro |
After conversion: where JPGs go
- Google Photos: use Backup and Sync or upload the JPG folder in browser.
- Family email: attach JPG, never HEIC—see HEIC email attachment guide.
- USB for parents: FAT32 sticks need <4 GB per file; JPGs rarely hit that—HEIC+MOV Live Photos do.
Stop future HEIC pain (optional)
Settings → Camera → Formats → Most Compatible saves new shots as JPEG. Existing library stays HEIC until converted. Read why iPhone uses HEIC before switching permanently—you will lose storage efficiency.
