Supports: PSD
PSD is Adobe Photoshop's native working format — layers, masks, smart objects, adjustment layers, and editable text live in one file, often weighing 50-300 MB for a real design. HEIC (Apple's HEIF/HEVC container, introduced with iOS 11 in 2017) is the modern mobile photo format: typically half the size of JPEG at the same visual quality, and the native format for iPhone, iPad, Mac Photos, and iCloud Photo Library. Common reasons to convert PSD → HEIC:
| Property | PSD | HEIC |
|---|---|---|
| Purpose | Photoshop working file (editable) | Mobile photo / final delivery |
| Layers / masks / smart objects | Yes (preserved) | No (flattened composite only) |
| Compression | Lossless, layer-aware (RLE / ZIP) | Lossy HEVC (very efficient) |
| Transparency | Yes (full alpha + layer masks) | Yes (8-bit alpha) — viewer support varies |
| Typical file size | 50-300 MB for layered designs | 1-4 MB for flattened design |
| Color depth | 8 / 16 / 32-bit per channel | 8 / 10-bit per channel |
| Color modes | RGB, CMYK, Lab, Grayscale, Indexed | RGB only |
| Native viewer | Photoshop, Photopea, Affinity, GIMP | iOS, iPadOS, macOS, Windows 10+ (with HEIF extension), modern Android |
| Year introduced | 1990 | 2017 |
| Best for | Editing, archival masters | iPhone/iPad libraries, iCloud, AirDrop |
| Preset | Visual quality | Size vs flattened PSD | Best for |
|---|---|---|---|
| Highest | Visually identical at 100% zoom | ~3-5% of PSD | Archive proofs, masters you may print again |
| Very High (default) | Indistinguishable for normal viewing | ~2-3% of PSD | iPhone/iPad libraries, client review on Apple devices |
| High | Minor softening on close inspection | ~1-2% of PSD | iCloud uploads, casual sharing |
| Medium | Visible compression on detail areas | ~1% of PSD | Quick previews, reference thumbnails |
| Low / Very Low / Lowest | Heavier compression artifacts | <1% of PSD | Tiny preview / contact-sheet use only |
No — HEIC is a single-image format. The conversion flattens every visible layer, layer mask, adjustment layer, and smart object into one composite RGB image, exactly like Photoshop's "Flatten Image" or "Save a Copy → HEIC" command. Hidden layers are not included. Keep the original PSD as your editable master and re-convert when the design changes.
No. The PSD is parsed and rasterized in your browser session without ever touching Adobe software. PSDs created in Photoshop, Photopea, Affinity Photo, GIMP, or Krita all decode the same way. Smart objects and most live filter effects are baked into the rasterized output.
CMYK PSDs (typical for print artwork) are mapped to RGB during rasterization because HEIC only stores RGB. Out-of-gamut CMYK colors get clipped to the closest sRGB equivalent, so colors may shift slightly versus the CMYK original. If accurate print color matters, keep the PSD/CMYK as your master and only use HEIC for screen previews on Apple devices.
Windows 10 and 11 support HEIC after installing the free HEIF Image Extensions from the Microsoft Store. macOS, iOS, iPadOS, and modern Android (10+) handle HEIC natively. Older Windows 7 / 8 boxes and legacy Linux setups may not — convert to JPG instead with PSD to JPG if you're sharing with mixed-platform recipients.
Partly. HEIC supports an 8-bit alpha channel, but Apple's Photos app and many third-party viewers ignore it and composite over a default background. That's why this converter offers a flatten background color — pick white (default) for portfolio shots, black for OLED-friendly previews, or another color to match your design context. If you need guaranteed-transparent output, PSD to PNG is the safer target.
Dramatically smaller — but it's not a fair comparison since PSD stores editable layers and HEIC stores a single flattened image. A 200 MB layered PSD typically flattens to a 1-4 MB HEIC at Very High quality. Compared to a flattened JPG export of the same design, expect HEIC to be roughly 50% smaller at equal visual quality, which is why Apple switched its default camera output to HEIC in 2017.
No. Once layers are flattened they cannot be reconstructed. HEIC is a delivery and storage format, not an editable working format. Always keep your original PSD as the editable master. If you only need a flat single-layer copy back in Photoshop, convert the HEIC to PNG first and re-import that as a single layer.
HEIC if your audience is on Apple devices or modern Windows / Android — you get roughly half the file size at equal visual quality. JPG (see PSD to JPG) if you need universal compatibility with every browser, every email client, and every legacy device. HEIC is the better long-term choice for Apple-centric workflows; JPG is the safer broad-compatibility one.
Yes — drop in an entire design folder, brand-asset library, or client deliverables set. Each PSD rasterizes and encodes in parallel within your browser session and downloads individually or as a single ZIP. Settings can apply uniformly across the batch or be overridden per file.
