How it works

  1. Step 1:

    Drop the JPEG file on the orange block above, or press “Choose JPEG”.

  2. Step 2:

    Press “Convert to HEIC”. The block shows the progress while the server converts the file.

  3. Step 3:

    Press “Download” to save the HEIC file. On Free the link works for 24 hours.

How JPEG to HEIC conversion works

JPEG is an image format: it uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. HEIC is an image format that applies H.265 (HEVC) intra-frame compression, which usually yields smaller files than JPEG at similar quality, used natively by Apple devices. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. Converting between these two formats is common when the source application does not support HEIC natively or when the target platform only accepts HEIC. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and returned through a private download link that expires after 24 hours on Free.

Image Tip: For photos, Medium quality offers the best balance. For graphics with text or sharp edges, use High or Maximum quality to preserve clarity.

When to convert

What the HEIC file is good for and why people convert to it.

  • Smaller storage than JPEG by using HEVC/HEIF compression
  • Good perceived quality at lower bitrates for photos and gradients
  • Save iPhone storage by converting downloaded JPEG photos to HEIC
  • Send high-quality images in fewer bytes to mobile recipients

Where your file goes

  • It travels to our server over an encrypted HTTPS connection and is converted there.
  • The HEIC file comes back as a private link. It stops working after 24 hours on Free and 7 days on paid plans, and then the files are deleted.
  • Want the file to stay on your device? Private Mode converts images right in the browser. Open Private Mode

Questions and answers

What people ask before converting JPEG to HEIC.

Will converting JPEG to HEIC improve image quality?
HEIC can look better at the same perceived quality because HEVC is more efficient, but it cannot restore details lost in the original JPEG. If the JPEG was already heavily compressed, HEIC will still be limited by that source.
Why is HEIC typically smaller than JPEG?
HEIC (HEIF) uses HEVC-based compression, which usually achieves the same visual quality at lower file sizes than JPEG’s older DCT-based lossy method.
Is HEIC transparent like PNG?
HEIC generally does not support full PNG-style alpha transparency in the same ubiquitous way; some HEIF variants may include transparency, but compatibility is uneven. Most photo workflows treat HEIC as non-transparent.
Will HEIC files open on all devices?
HEIC is natively supported on modern Apple devices, but not all desktop apps or older browsers handle it without a viewer/codec. Checking recipient compatibility is important.
