How to Upscale Images for Social Media: Instagram, LinkedIn & Beyond

Instagram, LinkedIn, and Facebook all compress your images on upload. Starting at higher resolution is the only way to counteract this — here's how.

Every time you upload an image to Instagram, LinkedIn, Facebook, or Twitter/X, the platform recompresses it to reduce storage costs. This compression is aggressive — especially for JPEGs. The result is a posted image that looks softer and more artefacted than your original file. The only way to counteract platform compression is to start with a higher-resolution image than you need, so that even after compression, the result looks sharp.

Optimal Image Sizes for Each Platform (2025)

- Square post: 1080×1080px (minimum), 1440×1440px (ideal)

- Portrait (4:5): 1080×1350px minimum

- Landscape (1.91:1): 1080×566px minimum

- Stories/Reels: 1080×1920px

- Profile photo: 400×400px minimum, 1000×1000px recommended

- Post image: 1200×628px minimum (1.91:1 landscape)

- Article cover: 1920×1080px recommended

- Post image: 1200×630px minimum

- Cover photo: 1640×624px

- Profile photo: 720×720px minimum

- Post image: 1200×675px (16:9) or 1200×1200px (square)

- Header: 1500×500px

- Standard pin: 1000×1500px (2:3 ratio)

- Infographic: 1000×3000px maximum height

Why Your Images Look Blurry After Uploading

Platform compression algorithms work by reducing the file size of your image using JPEG or WebP compression. This introduces:

Blocking artefacts: Visible 8×8 pixel squares at edges and in smooth gradients.

Chroma subsampling: Colour information is discarded, causing skin tones and subtle colour gradients to look flat and banded.

Detail loss: Fine textures — hair, fabric, background foliage — lose crispness and appear softened.

The platform's algorithm is designed to balance file size against perceived quality at the platform's standard display size. If your source image is exactly at the minimum size, the compressed version at display size will look noticeably degraded. If your source image is 2× or larger than the display size, the compression affects a resolution that exceeds the display size — meaning the displayed image looks sharp even after compression.

The Social Media Upscaling Workflow

Step 1 — Identify your source image's current dimensions. If it's close to platform minimums (e.g., 900×900px for an Instagram post), upscaling will meaningfully improve post quality.

Step 2 — Upscale to 1.5–2× the target platform dimensions. For Instagram square posts, target 2160×2160px (2× the 1080px display resolution). After platform compression, this will display at near-native 1080p quality.

Step 3 — Use Normal upscale for speed or Pro AI for maximum sharpness. For social media content produced at high volume, Normal (1 credit) is efficient. For key portfolio shots or hero content, Pro AI (2 credits) produces noticeably sharper fine detail.

Step 4 — Export as PNG for graphics, JPEG for photos. For photo posts, JPEG at high quality (90%+) is fine. For graphics with text or logos, use PNG to preserve crisp edges before the platform applies its own compression.

Tips Specific to Each Platform

Instagram: Upload at exactly 1080px or 1440px wide. Instagram sharpens images uploaded at 1080px natively — going larger than 1440px provides no additional benefit.

LinkedIn: LinkedIn is particularly aggressive with portrait image compression. Profile photos and headshots benefit most from upscaling before upload — target 1000×1000px minimum.

Pinterest: Tall pins (2:3 ratio) perform best. Upscaling a 600×900px photo to 1200×1800px significantly improves how it renders in the feed.

Twitter/X: The 1200×675px format is actually losslessly previewed on desktop. Uploading at exactly 1200×675px or 2× (2400×1350px) gives the best results.

Frequently Asked Questions

Platform algorithms do not directly rank based on image resolution. However, sharper images typically receive higher engagement (likes, shares, saves), and engagement is the primary signal for algorithmic reach on Instagram and Pinterest.

For photos: JPEG (Instagram, Facebook, Twitter). For graphics: PNG (all platforms — preserves text sharpness). For video thumbnails: PNG with 72+ DPI.

Yes — if the blur is from low resolution rather than motion or focus blur. A 720p-quality selfie from an older phone benefits significantly from 2× Pro AI upscaling before posting.
