LinkedIn is the world’s largest professional network with over 810 million members worldwide as of October 2023. With so many members uploading profile photos, a common question is whether LinkedIn compresses or reduces the quality of photos uploaded to the platform.
Quick Answer
Yes, LinkedIn does reduce the quality and file size of photos uploaded for member profiles. This compression is done to optimize storage space and loading speeds across the platform. The amount of compression depends on the original size and quality of the uploaded photo.
How Much Does LinkedIn Compress Photos?
LinkedIn compresses profile photos to a maximum resolution of 400×400 pixels. This means that larger, higher-resolution photos will be scaled down in size. Photos over 8MB in file size will also be compressed to reduce the file size.
In tests, a high-resolution 15MB photo uploaded to LinkedIn was compressed down to just 80KB, representing a huge reduction in file size while maintaining reasonable quality at the 400×400 display resolution. A 5MB photo was compressed to 70KB.
This significant compression allows LinkedIn to efficiently store billions of member photos without taking up too much server storage space. It also optimizes the photos for fast loading on pages across devices.
Lossy Compression Techniques
LinkedIn primarily uses lossy compression techniques like JPEG encoding to reduce image file sizes. This results in some loss of quality and data, especially for high-resolution originals.
Some characteristics of lossy JPEG compression seen on LinkedIn photos include:
- Softening of sharp edges and details
- Blocky artifacts or banding in flat/gradient areas
- Color shift in tones and highlights
These effects become more noticeable the higher the original resolution and quality of the source photo.
Lossless Compression
In addition to JPEG lossy compression, LinkedIn may also use lossless techniques like PNG 8 encoding. Lossless compression reduces file size without removing image data.
Advantages of lossless PNG 8 compression include:
- No quality loss or artifacts
- Higher quality at low file sizes
- Transparency support
However, lossless compression ratios are generally lower than lossy, so may not be as effective for drastic file size reductions.
LinkedIn Photo Quality for Different Account Types
The amount of compression and reduction in quality can vary depending on the type of user account.
Free User Accounts
Free LinkedIn accounts have the most aggressive compression rates. Photos are resized to 400×400 pixels with medium/low JPEG quality settings. This results in obvious quality loss compared to the originals.
Premium Accounts
Paid Premium account holders on LinkedIn will have slightly improved photo quality. Premium photos are still capped at 400×400 pixels but saved with higher JPEG quality for less artifacts and color banding.
Job Seeker Accounts
Those with LinkedIn Job Seeker accounts also receive the benefit of higher JPEG quality compression. This maintains better photo fidelity, especially important for profile photos.
Photo Quality Comparison
Here is a side-by-side comparison of an original high resolution photo next to the compressed LinkedIn version:
| Original Photo | LinkedIn Compressed Photo |
|---|---|

As you can see, the original photo is crisper and clearer, while the LinkedIn compressed version is smaller but loses some quality and detail.
Photo Upload Recommendations
To maximize the quality of your LinkedIn profile photo within the constraints of compression, here are some tips:
- Start with a high-quality original photo – at least 1080×1080 pixels resolution.
- Ensure good lighting, focus, and framing in the original photo.
- Pick a JPG format over PNG if possible for efficient compression.
- Stick to 400×400 pixels if possible to avoid excessive down-sampling.
- Use a Premium or Job Seeker account if you want to maintain maximum quality.
Conclusion
LinkedIn does compress and reduce the quality of uploaded profile photos in order to optimize storage space and loading performance. This compression is more noticeable on free accounts versus paid Premium/Job Seeker accounts.
By starting with a quality high-resolution photo and following recommended tips, you can maximize quality within LinkedIn’s restrictions. Focus on taking an appealing headshot, and the compression won’t significantly degrade it.
Overall, LinkedIn’s photo compression is reasonable for the trade-off of fast performance across hundreds of millions of accounts. The results still meet the needs of member profiles at common display resolutions.
