Best Export Settings for iPhone Instagram
Why iPhone Photos Look Worse on Instagram
You edit your photo.
It looks perfect in Lightroom Mobile.
Soft highlights.
Natural skin tones.
Balanced contrast.
Then you upload it to Instagram.
And suddenly:
• the photo looks softer
• colors shift slightly
• shadows become darker
• grain looks harsher
This happens because Instagram compresses every image you upload.
If you export incorrectly, Instagram compresses your image even more aggressively.
The solution is simple.
Export your photos in the format Instagram expects.

The Best Instagram Export Resolution
Resolution is the most important setting.
Instagram automatically resizes large images.
To avoid aggressive compression, export at Instagram’s preferred sizes.
Recommended resolution:
Vertical posts (best performing)
1080 × 1350 px
Square posts
1080 × 1080 px
Landscape posts
1080 px width
If you upload larger images such as 3000px or 4000px files, Instagram will downscale them.
This creates visible quality loss.

Best Lightroom Mobile Export Settings
Inside Lightroom Mobile, export using the following settings.
Format
JPEG
Color Space
sRGB
Dimensions
Custom → 1080 px (or 1080 × 1350 for vertical)
Quality
80–90
Sharpening
Off
These settings allow Instagram to compress your image less aggressively.
Why Exporting at 100% Quality Is a Mistake
Many photographers assume exporting at 100% quality produces the best results.
But Instagram often compresses high-quality files more aggressively.
Large files trigger heavier recompression.
The sweet spot is:
Quality 80–90
This keeps file size manageable while preserving detail.
The Importance of sRGB Color Space
Color space determines how colors appear on different devices.
Instagram only supports sRGB color profiles.
If you export in:
• AdobeRGB
• ProPhoto RGB
your colors can appear:
• dull
• shifted
• washed out
Always export using:
sRGB
This guarantees consistent color across devices.
Should You Add Sharpening?
Instagram applies its own sharpening algorithm.
If you add sharpening during export and Instagram sharpens again, the result can look harsh.
Recommended export setting:
Sharpening → Off
Let Instagram apply the final sharpening pass.

How Grain Behaves on Instagram
Film-style edits often include grain.
Instagram compression can affect grain texture.
Fine grain can turn into blotchy noise if exported incorrectly.
Best approach:
Keep grain subtle.
Recommended grain values:
Amount
10–20
Size
20–30
This maintains texture without triggering compression artifacts.
Why Film Edits Are More Sensitive to Compression
Film-inspired edits rely on subtle tonal transitions.
These include:
• soft highlight roll-off
• gentle contrast
• subtle color grading
• natural grain
Instagram compression favors:
• high contrast
• strong edges
• bright colors
This means subtle film edits can flatten if exported incorrectly.
Correct export settings protect the film aesthetic.
iPhone Camera Files vs Instagram Compression
Modern iPhones capture extremely high resolution images.
Typical file sizes can exceed:
• 12MP
• 24MP
• 48MP (Pro models)
Uploading full-resolution files forces Instagram to shrink them dramatically.
This increases compression artifacts.
Exporting directly at Instagram resolution avoids this problem.
How to Export From Lightroom Mobile (Step-by-Step)
1️⃣ Open your edited photo
2️⃣ Tap Export As
3️⃣ Choose JPG
4️⃣ Set Dimensions → Custom → 1080px
5️⃣ Set Quality → 80–90
6️⃣ Disable sharpening
7️⃣ Save to camera roll
8️⃣ Upload directly to Instagram
Avoid re-saving the image through apps like WhatsApp or AirDrop compression.
Test Your Export Settings
The easiest way to see the difference is by testing.
Export the same image three ways:
• full resolution
• 2000px
• 1080px
Upload them privately.
The 1080px version usually looks the sharpest.
This happens because Instagram does not need to resize it.
Try the Free Film Preset
If you want to see how well film-style edits survive Instagram compression, test a preset.
Download the free film preset and apply it to:
• an outdoor photo
• a portrait
• a travel image
Export using the settings above and compare the results.
Starter Pack (Best Presets for Instagram)
If you want presets designed specifically for social media photography, start with the Starter Pack.
These presets are calibrated for:
• iPhone photography
• Lightroom Mobile workflows
• Instagram compression behavior
• consistent color across posts
Final Thoughts
Instagram compression is unavoidable.
But poor export settings make it much worse.
By exporting at the correct resolution, color space, and quality level, you can preserve far more detail in your photos.
For iPhone photographers using Lightroom Mobile, following a consistent export workflow ensures your images remain sharp, balanced, and professional on social media.
FAQ
What is the best resolution for Instagram?
1080 × 1350 pixels for vertical posts produces the best results.
Should I export at 300 dpi?
DPI does not affect digital uploads. Resolution in pixels is what matters.
Why do my Instagram photos look blurry?
Instagram automatically resizes and compresses large files. Exporting at 1080px prevents heavy compression.
Should I use JPEG or PNG for Instagram?
JPEG is recommended because Instagram compresses PNG files more aggressively.
