Generation loss — quality may degrade
JPG uses lossy compression, and so does HEIF. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your JPG file may contain IPTC, ICC metadata. HEIF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 24-bit → 10-bit
JPG stores up to 24 bits per channel, but HEIF supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

About JPG to HEIF Conversion
JPG (introduced 1992) and HEIF (introduced 2015) are both image formats, but they differ in important ways. JPG (JPEG) uses lossy compression, making it ideal for photographs and complex images where small file size matters more than pixel-perfect quality. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices.
Full Name: JPG uses JPEG Image, while HEIF uses High Efficiency Image Format. Compression: JPG uses Lossy, while HEIF uses Lossy. Transparency: JPG uses No, while HEIF uses No.
When you convert JPG to HEIF, the goal is to upgrade to a modern format. JPG uses lossy compression, and so does HEIF. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. Understanding these technical differences helps you choose the right format for your workflow.
Your JPG file is decoded and re-encoded as HEIF. The conversion involves 4 steps: (1) your jpg file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in heif format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you When you specifically need a HEIF file for your workflow. For the opposite direction, CocoConvert also supports HEIF to JPG conversion.
How to Convert JPG to HEIF
- 1
Upload .jpg file
Select your JPG file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .heif
Set HEIF as the output format. The converter uses optimal settings based on the JPG→HEIF conversion profile.
- 3
Convert
The server-side engine decodes your JPG file and re-encodes it as HEIF. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .heif file. Multiple output files can be downloaded together.
What Happens When You Convert JPG to HEIF
Your JPG image is decoded into raw pixel data, then re-encoded as HEIF. Quality degrades each time lossy data is re-encoded. Convert from the original source when possible.
Your JPG file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using High Efficiency Image Format's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIF supports it
The HEIF file is saved and ready for download

Should You Convert JPG to HEIF?
When to Convert
- ✓When you specifically need a HEIF file for your workflow
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
Common Mistakes When Converting JPG to HEIF
"I'll convert to HEIF and then back to JPG — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going JPG → HEIF → JPG will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
What is the difference between JPG and HEIF?
JPG (JPEG) uses lossy compression, making it ideal for photographs and complex images where small file size matters more than pixel-perfect quality. HEIF stores images using highly efficient HEVC compression, commonly used on Apple devices. Full Name: JPG uses JPEG Image, while HEIF uses High Efficiency Image Format. Compression: JPG uses Lossy, while HEIF uses Lossy. Transparency: JPG uses No, while HEIF uses No.
Does JPG to HEIF conversion affect quality?
JPG uses lossy compression, and so does HEIF. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Which format has better compression, JPG or HEIF?
JPG uses lossy compression. HEIF uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does JPG to HEIF conversion take?
Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is JPG or HEIF better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
