Need help?How to Convert WebP to HEIF Online
- Upload Your WebP File: Drag and drop or click "+ Add Files" to select one or many
.webpimages. Batch is supported — the same advanced settings apply to every file in the queue. - Pick a Quality Preset: Default is Very High (Recommended). Choose Highest if you intend to keep the HEIF as a master, High or Medium for sharing, or Low/Lowest to squeeze the file when you need to fit a Mail attachment cap.
- Set Resolution (Optional): Keep original, scale by Resolution Percentage, pick a Preset Resolution (e.g. 1080P, 1440P, 2160P), or enter custom Width and Height with aspect ratio locked.
- Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.
Why Convert WebP to HEIF?
WebP is Google's web-first image format built on the VP8 codec, while HEIF (High Efficiency Image File Format, ISO/IEC 23008-12) is an ISO/MPEG container that normally carries an HEVC/H.265 bitstream — the .heif/.heic files iPhones have shot since iOS 11 in September 2017. Converting moves an image from a web-distribution format to one that slots cleanly into the Apple Photos library, supports the same 10-bit and wide-gamut metadata as your camera roll, and is roughly 40-50 % smaller than the equivalent JPEG at matched quality.
- Importing web assets into Apple Photos — drop a HEIF straight into iCloud Photos and it indexes alongside iPhone shots; a WebP shows up as an unsupported attachment and has to be re-encoded by macOS.
- HDR and wide-gamut workflows — HEIF stores up to 16-bit-per-channel data and Display-P3 / Rec.2020 ICC profiles. WebP is capped at 8-bit Y'CbCr 4:2:0 (Wikipedia), so HDR pulled from a WebP source is the best you can fake from 8-bit, not real HDR.
- Tighter storage with the same look — at matched perceptual quality, HEIC files run about 10-25 % smaller than WebP on typical photographic content because HEVC's intra-frame prediction handles smooth gradients and noise better than VP8.
- Sharing into Messages, AirDrop, and Mail — HEIF is native on iOS 11+ and macOS High Sierra 10.13+; it sends without a Mail-side re-encode that would otherwise blow up file size.
- Pipeline parity with iPhone output — designers handing assets back to iOS or watchOS engineers often need HEIF so the same decoder path (
ImageIO,PHAsset) handles every image. - Future-ready container — HEIF also accepts AV1 (saved as
.avif) and other codecs, so re-encoding once to HEIF leaves you a path forward without another round-trip.

Quality Preset Guide
| Preset | Use When | Trade-off |
|---|---|---|
| Highest | Archival masters; you may re-edit later | Largest file; smallest visible difference vs source |
| Very High (default) | Sharing a photo at full perceived fidelity | Visually transparent for most photographic content |
| High | iCloud / Photos imports of casual shots | Slight chroma smoothing under heavy zoom |
| Medium | Email, Messages, social posts | Visible compression on flat gradients and skies |
| Low / Lowest | Squeezing under a strict size cap (e.g. CRM upload) | Blocking and banding likely on noise-heavy areas |
HEIF vs HEIC — Same Family, Different Extensions
HEIF is the container; HEIC is the most common variant inside it. Per the standard, files whose images are HEVC-encoded must use the .heic extension (or .heics for sequences), while .heif is reserved for the broader mif1/msf1 brand that may carry any supported codec (Wikipedia). Practically: every .heic file is a .heif file, but not every .heif file is a .heic. If you need the Apple Photos default specifically, use WebP to HEIC instead.
Frequently Asked Questions
Is HEIF the same as HEIC?
No — HEIF is the container defined in ISO/IEC 23008-12; HEIC is the brand used when the image inside that container is encoded with HEVC/H.265. iPhones write .heic by default; tools that target the general container write .heif. Both can be opened by the same software (iOS 11+, macOS 10.13+, Windows 10/11 with the HEVC codec, Android 10+).
Why convert WebP to HEIF instead of just keeping the WebP?
If the file is staying on the web, keep the WebP — it has near-universal browser support. Convert to HEIF when the destination is the Apple ecosystem (Photos, Messages, AirDrop), when you want a 10-bit / wide-gamut container that WebP physically cannot encode, or when you want roughly 10-25 % smaller files at the same visual quality on photographic content.
Will my WebP's transparency be preserved?
Yes for HEIC-encoded HEIF — the format supports an 8-bit alpha channel. Some downstream viewers (especially older Windows tools and non-Apple image apps) ignore the alpha and composite onto white, so test the consumer of the file before assuming PNG-level transparency behaviour. If you specifically need rock-solid alpha across every viewer, WebP to PNG is a safer pick.
What about animated WebP — does HEIF carry the animation?
HEIF supports image sequences (the same mechanism that stores iPhone burst shots and Live Photo stills), not GIF-style timed animation with looping. Most converters — including this one — export the first frame of an animated WebP as a single HEIF still. If you need a moving image, convert WebP to MP4 or to an animated AVIF instead.
How big should I expect the HEIF to be compared to the WebP?
For a typical photograph at matched perceptual quality, expect the HEIF to be roughly 10-25 % smaller than a quality-75 lossy WebP. Screenshots and flat graphics see less savings because VP8L (lossless WebP) is already efficient on text and large solid areas; HEIF's HEVC intra-coding shines on photographic noise and gradients.
Why won't the converted HEIF open in Chrome or Firefox?
Because no Chromium or Gecko browser ships an HEIF/HEIC decoder as of 2026 — only Safari 17+ does (Can I Use). HEVC patent-licensing costs are the usual cited reason. On desktop, open the file in Preview (macOS), the Photos app (Windows 10/11 with the free HEVC Video Extensions), or any image viewer with HEIF support like IrfanView or GIMP 2.10+.
Does this converter strip EXIF, GPS, or colour-profile metadata?
The converter preserves embedded ICC profiles and standard EXIF blocks where the source carries them. GPS coordinates inside EXIF are kept — strip them in your photo app before upload if you don't want location data in the output.
Is there a file size limit?
Processing happens on our servers: files are uploaded over an encrypted connection, processed, and outputs are deleted automatically after a few hours. There is no per-file watermark and no sign-up gate. For very large batches, convert in smaller groups if upload time is a concern.
What if I actually want a JPEG instead?
Pick the right destination for the recipient: if the receiver is on Android, Windows without the HEVC codec, or anywhere on the web, HEIF to JPG or going straight from WebP to JPG is the lower-friction path. HEIF is the right answer when the destination is Apple-native or HDR/wide-gamut-aware.
