The biggest difference between HEIC to JPG converters is whether your photos ever leave your device. This guide compares four of them (sakuttoAI, CloudConvert, Convertio, and HEIC Digital) on where files are processed, how long a server keeps them, supported formats, and price. The answer matters most for one private photo, and least for a batch you don't mind uploading.
Check whether your device already opens HEIC first
iPhone and Mac have read HEIC natively since 2017
Apple built HEIF and HEVC support into iOS 11 and macOS High Sierra, so any iPhone 7 or later, and any Mac running High Sierra or newer, opens and edits HEIC photos without extra software. On a Mac, exporting to JPEG or PNG takes a few clicks in Photos or Preview: choose File > Export, then pick the format.
Windows needs a free Microsoft Store extension
Windows doesn't read HEIC out of the box. Microsoft offers a free HEIF Image Extension, plus a separate HEVC Video Extensions package that Windows needs to actually decode the image data inside a .heic file. The image extension was listed at $0 in the US store as of September 5, 2026, but the video extension's price and availability vary by device and region, so check your own listing before assuming both are free.
"iOS 11 and macOS High Sierra introduced support for these new, industry-standard media formats"/"HEIF and HEVC offer better compression than JPEG and H.264, so they use less storage space on your devices and iCloud Photos"/"If you open an HEIF image in Photos or Preview on your Mac, choose File > Export, then choose a format such as JPEG or PNG before saving."View official source →
"The HEIF Image Extension enables Windows to read and write files that use the High Efficiency Image File (HEIF) format."/"The HEVC Video Extensions package must be installed in order to view images stored in HEIF files that use the .heic, .hif or .heif file extensions."View official source →
Where a converter processes your photos matters most
Browser-based conversion keeps files on your device
A browser-based converter decodes and re-encodes your HEIC file using your device's own processor, inside the browser tab. Nothing is uploaded, so there's no retention period to check and no upload to wait for. How fast it runs depends on your device.
Server-based conversion runs on a retention window
A server-based converter uploads your original file, converts it remotely, and sends back the result. That means your photo sits on someone else's server until the vendor deletes it, which in the tools below takes anywhere from under an hour to a full day. That window is the one number worth checking before you upload anything private.
Four HEIC to JPG converters compared side by side
Only sakuttoAI keeps your photos on your device; the other three upload them and delete them anywhere from right after conversion to 24 hours later. The first table compares where each tool processes your photos, and the second compares batch conversion, output formats and price.
| Tool | Where photos are processed | Server retention |
|---|---|---|
| sakuttoAI | Your browser (never uploaded) | Not applicable (files never leave your device) |
| CloudConvert | CloudConvert's servers | Deleted automatically within 24 hours, immediately if you use the delete button |
| Convertio | Convertio's servers | Input files deleted instantly after conversion; output files deleted instantly on request or within 24 hours automatically |
| HEIC Digital | HEIC Digital's servers | Deleted automatically 1 hour after upload |
All four handle more than one file at a time, but they differ in what they can output and what the free tier covers. The catches: sakuttoAI needs a free account, and HEIC Digital outputs JPG only.
| Tool | Batch conversion | Output formats | Price |
|---|---|---|---|
| sakuttoAI | Yes, plus ZIP download | JPG, PNG, WebP | Free with a free account |
| CloudConvert | Yes | 200+ formats, including JPG, PNG, WebP | Free tier available |
| Convertio | Yes | Images, video, and audio formats | Free tier available |
| HEIC Digital | Yes | JPG | Free — vendor states no file-size limit and no daily quota |
Neither CloudConvert nor Convertio states its exact free daily limit on its privacy page. Check cloudconvert.com/pricing and convertio.co/pricing before relying on the free tier.
sakuttoAI processes everything in your browser
sakuttoAI converts HEIC to JPG, PNG, or WebP entirely on your device, with a quality slider from 10% to 100% for JPG and WebP output (PNG is lossless, so there's no quality setting to adjust). It accepts multiple files at once and bundles the results into a single ZIP download. It needs a free sign-in (email link or Google, no password), and free accounts get 3 tasks per day in total across all file tools; Pro is unlimited.
CloudConvert and Convertio delete files on a timer
CloudConvert's own privacy documentation states that files are removed automatically within 24 hours, or immediately if you use its delete button. It also supports well over 200 file formats beyond images.
Convertio's privacy documentation describes a two-stage deletion: input and temporary files disappear the instant conversion finishes, while output files are deleted instantly on request or within 24 hours otherwise. Both are reasonable choices if you need a format sakuttoAI doesn't offer, but both mean your original photo touches a server you don't control.

"We delete input files and all temporary files instantly after any file conversion. We delete output files instantly when the user clicks 'X' in the web panel, otherwise, output files are deleted after 24 hours automatically."View official source →
HEIC Digital needs no sign-up and deletes files after an hour
HEIC Digital states on its own site that every uploaded photo, whether opened for viewing or converted, is deleted automatically one hour after upload. It also advertises no file-size limit, no daily quota, and no registration requirement. That's the shortest retention window and the fewest restrictions of the three server-based tools here, though its output is limited to JPG.

No file size limits, no daily quotas, no registration required."View official source →
Which converter fits your situation: four quick picks
Skip the reviews above if you already know what matters most to you. Find that in the left column and take the pick next to it.
| If you need to... | Best choice | Why |
|---|---|---|
| Convert a private photo without uploading it anywhere | sakuttoAI | Runs entirely in your browser; nothing is sent to a server |
| Convert into formats beyond JPG, PNG, and WebP | CloudConvert | Supports 200+ formats total, not just images |
| Minimize how long a server keeps your file | HEIC Digital | Automatic deletion 1 hour after upload |
| Convert without creating an account | HEIC Digital | No sign-up required (sakuttoAI needs a free account) |
When in doubt, default to sakuttoAI: it covers the most common case, a private photo converted once, without asking you to trust a server's retention policy. Switch to one of the server-based tools only when you need a format or feature sakuttoAI doesn't offer.
Frequently asked questions
Do Windows 11 and recent Macs still need a HEIC converter?
Often not, for simply viewing a photo. Recent Macs and iPhones read HEIC natively, and Windows can read it once the free HEIF Image Extension is installed. A converter still earns its keep for batch jobs, quality control, or output formats those built-in viewers don't offer.
Which converter keeps photos on a server the shortest time?
HEIC Digital states the shortest window: files are deleted automatically one hour after upload. CloudConvert and Convertio both delete files within 24 hours, faster if you delete them manually. sakuttoAI keeps nothing on a server at all, since conversion runs in your browser.
Can I convert HEIC to JPG without installing any software?
Yes. All four tools in this comparison run in a web browser, so there's nothing to install on your phone or computer. HEIC Digital also works without an account; sakuttoAI needs a free one, but the conversion itself happens on your device rather than a server.
Does HEIC to JPG conversion remove EXIF data?
It depends on the tool. Most converters preserve EXIF data in the JPG output, but some strip it during conversion. If metadata matters to you, check the converted file's properties before deleting the original HEIC.
Summary
What happens to your photo after you hit convert is the part worth deciding on first. sakuttoAI processes everything in your browser and never uploads a file, so it's the only option here with no retention window to check. If you need a format beyond JPG, PNG, or WebP, look at CloudConvert or Convertio; both publish a deletion window you can read before uploading anything sensitive.
