  2. 2
    Pick JPEG or PNG Choose JPEG for universal photo sharing and smaller file sizes, or PNG for lossless perfection.
  3. 3
    Fine-Tune Quality The default 90% quality produces gorgeous results with almost no perceptible difference from original camera clarity.
  4. 4

💡 Tips for Apple Photo Conversion

Why Apple Uses HEIC iPhones save pictures in HEIC because it uses half the storage space of JPEG, but most non-Apple devices and web browsers cannot view them natively yet.
JPEG vs PNG for Photos Always select JPEG for camera photos. PNG files are lossless and will result in much larger file sizes (often 10MB+ per photo) without noticeable visual improvement.
Large Photo Batches Because decoding occurs in your browser RAM, converting in batches of 15–25 photos keeps your device responsive and fast.

Under the Hood: WebAssembly libheif Engine & Client-Side Transcoding

HEVC intra-frame decoding, 32-bit RGBA pixel buffer translation, and canvas rasterisation.

Details

WebAssembly Transcoding Pipeline

Apple devices encode photos using High Efficiency Video Coding (HEVC / H.265) intra-frame compression encapsulated in HEIF containers. Because standard web browsers cannot natively render HEIC directly inside standard <img> elements, BWTools utilises an in-browser WebAssembly port of libheif.

Pixel Buffer Allocation & Memory Isolation

The decoder translates raw binary byte buffers into uncompressed 32-bit RGBA pixel arrays directly within an isolated execution thread. HTML5 Canvas primitives then encode these pixel arrays into standard JPEG or PNG representations at the exact target quality specified, ensuring maximum performance with zero bandwidth waste.

Format & Export Specifications

Output Format MIME Type Compression Alpha (Transparency) Ideal Use Case
JPEG (.jpg) image/jpeg Lossy (Adjustable 20%–100%) No Everyday photography, web sharing, eBay & e-commerce
PNG (.png) image/png Lossless (Pixel-perfect) Yes High-fidelity archiving, graphic design, overlays

❓ Frequently Asked Questions

Why does Apple use HEIC by default instead of JPEG?

HEIC delivers roughly 50% better compression than legacy JPEG at identical visual quality, saving huge amounts of storage on iPhones. However, Windows PCs, older Androids, and many websites cannot open it natively without third-party converters.

Is there a limit on how many files I can convert at once?

There are no arbitrary server limits. Because processing runs on your local computer or phone hardware, you can convert dozens of photos at once. For very large batches (50+ photos), doing 15–25 at a time ensures fast, smooth browser performance.

Are my converted files stored anywhere on your servers?

Never. BWTools has zero backend processing servers. Everything is decoded and converted inside your browser sandbox. Your photos and metadata never leave your computer.

Does converting from HEIC to JPEG lose photo quality?

At our default 90% quality setting, the output JPEG is visually indistinguishable from your original Apple photo. If you need 100% mathematical bit-for-bit lossless output, you can select PNG format.
