See how our WebAssembly HEVC decoder translates Apple container files into standard sRGB JPEGs with customizable compression ratios.
Decoded the high-efficiency HEVC image tile grid directly in browser memory while preserving exact 5712×4284 pixel dimensions and natural skin tones—ready to open in Windows Photo Viewer or upload to legacy government portals.
Processed an entire album of iPhone travel photos sequentially in client-side RAM without waiting for cloud uploads or hitting "Max 5 Files per Day" paywalls, then bundled all 35 JPEGs into a single ZIP.
Converted an iPhone studio product shot into a lightweight 640 KB JPEG using the 0.7 quality setting, bypassing "Unsupported File Extension .heic" errors on older WordPress and ERP dashboards.
Since iOS 11, iPhones and iPads save photos in Apple’s .heic (High Efficiency Image Coding) format by default. While great for saving iPhone storage, HEIC files trigger constant compatibility roadblocks outside the Apple ecosystem:
Transferring photos from an iPhone to a Windows 10/11 PC via USB cable or iCloud Drive often leaves you with unreadable .heic icons, and Microsoft Store charges for the official HEVC Video Extensions. Our browser decoder converts them to .jpg for free.
Visa application portals, university submission systems, tax websites, and older CMS platforms strictly require .jpg or .png attachments. Convert your iPhone document photos to compliant .jpg files in seconds.
Most online HEIC converters upload your private family photos, passports, or medical receipts to remote Linux servers for ImageMagick processing. Our tool runs heic-to WebAssembly locally—your photos never leave your device.
Our client-side decoder is engineered to handle standard Apple iOS/iPadOS photo containers with zero server round-trips:
Files ending in .heic or .HEIC captured by iPhone (iOS 11 through iOS 18+), iPad, or exported from macOS Photos.
Select or drag 1 to 100+ .heic photos at once. Because conversion uses your local CPU/RAM rather than network bandwidth, there are no daily file count caps or 5 MB upload limits.
Supports full 12MP (4032×3024), 24MP (5712×4284), and 48MP (8064×6048) iPhone sensor resolutions. Output .jpg dimensions match the source pixel width and height 1:1.
Default 0.8 (80%) delivers visually lossless clarity at compact file sizes. Slide to 1.0 for maximum archival quality or down to 0.5–0.7 to meet strict government portal KB limits.
Drag one or multiple .heic / .HEIC files into the blue upload zone, click "Select Files" to browse your computer or phone, or click "Try Sample iPhone HEIC Photo" to test immediately.
Review your queued files, use "Add More" to append additional photos, and adjust the Quality slider between 0.1 and 1.0 (default 0.8) to balance visual sharpness and file size.
Press the green "Convert All" button. Watch the status indicator next to each file change from a spinning loader to a green checkmark as the WebAssembly decoder renders each .jpg in memory.
Click the download icon next to any specific photo to save it individually, or click "Download All (ZIP)" to package every converted .jpg into heic-converted.zip in one click.
Baseline .jpg is the most universally supported image format on Earth—compatible with every operating system, browser, and software built since 1992:
Submit ID photos, signed forms, and receipts taken on your iPhone to strict legacy web forms that reject .heic extensions.
Import converted JPEGs straight into Windows Photo Viewer, PowerPoint, older Adobe Photoshop CS6/CC versions, or accounting software without installing third-party codec packs.
Pass your converted .jpg of a handwritten notebook straight into our Handwriting to Text OCR tool, or turn a portrait into favicons using our Image to Icon Generator.
Translating modern Apple container features into baseline 8-bit JPEG involves three known technical trade-offs:
iPhone Pro displays use an embedded Apple HDR Gain Map inside the HEIC container to boost screen brightness up to 1600 nits. Standard .jpg is an 8-bit SDR (Standard Dynamic Range) format.
Our decoder automatically tone-maps the image into standard sRGB so colors look accurate and balanced across all non-HDR Windows monitors, printers, and web browsers.
A .heic container can store multiple frames (such as burst shots or dynamic wallpapers), whereas a .jpg file can only hold a single flat image frame.
The converter automatically extracts and converts the primary keyframe (cover photo) selected in your iPhone Photos app.
iOS 16+ "Lift Subject from Background" stickers saved as HEIC contain an alpha transparency channel, but the JPEG specification does not support transparency.
If you need to preserve transparent backgrounds for web graphics or icons, use our SVG to PNG or PNG Compressor tools which maintain full 32-bit RGBA alpha channels.
See how client-side WebAssembly decoding compares against cloud upload converters and paid OS store codecs:
| Comparison Metric | iSVGtoPNG Local HEIC to JPG | Cloud-Upload Online Converters | Microsoft Store HEVC Extension |
|---|---|---|---|
| Privacy & Data Security | 100% Local browser RAM (Photos never leave your device) | Uploads your private photos to third-party remote servers | Local OS decoding |
| Batch Limits & Paywalls | Unlimited batch files & zero daily caps (100% Free) | Usually capped at 2–5 files unless you buy a subscription | Costs $0.99 and still requires manual "Save As" per photo |
| JPEG Quality Control | Interactive 0.1–1.0 quality slider + instant ZIP bundling | Fixed compression settings with slow server download queues | No batch conversion or quality slider built into Explorer |
| Cross-Platform Support | Works on Windows, macOS, Linux, Chromebook & Android | Requires fast upload bandwidth for large 24MP/48MP files | Windows 10/11 only |
No—not a single byte leaves your computer or phone. This page uses the client-side heic-to WebAssembly library and JSZip directly inside your browser. You can load this page, turn off your Wi-Fi, and convert 100 private .heic photos completely offline.
The default 0.8 (80%) is the industry sweet spot: it produces an image virtually indistinguishable from the original .heic while keeping file size compact. Choose 0.9 or 1.0 for printing and archival, or 0.5–0.6 if you need to shrink file size under 500 KB for an online application form.
Apple .heic files are encoded using H.265 (HEVC) intra-frame compression divided into dozens of high-resolution tiles. Your browser CPU decodes all tiles, stitches the full 12MP or 24MP canvas in memory, and re-encodes it into baseline JPEG.
On your iPhone, open **Settings > Camera > Formats** and switch from "High Efficiency" to **"Most Compatible"**. Your iPhone will then save new photos directly as .jpg (note that this uses roughly twice as much storage space on your phone).
