Post Full Photos Without Cropping
When your photo doesn't match Instagram's aspect ratios, the app clips the edges. Our tool adds clean borders around your image so every pixel stays visible — no cropping, no distortion.
Choose 4:5 Portrait or 1:1 Square for your feed layout.
Keep "Fit Canvas" and pick white, black, or any custom color.

Why Instagram Blurs Your Photos
Instagram compresses images wider than 1080 pixels or taller than a 4:5 ratio (1080 × 1350 px). Pre-formatting your images prevents blur, unwanted cropping, and color shifts.
100% Private Processing
Everything runs inside your browser using HTML5 Canvas — your photos are never uploaded, stored, or transmitted anywhere.
Optimized for Instagram
Exports high-quality JPEG with sRGB color profiles for consistent display across iOS and Android.
Frequently Asked Questions
What is the best aspect ratio for Instagram posts?
The 4:5 Portrait format (1080 × 1350 px) occupies the most screen space as users scroll, yielding higher engagement than square or landscape photos.
How does the grid splitter avoid stretching?
The tool calculates total grid dimensions and scales your photo to fit cleanly with background padding — no distortion, no stretching.
Why does Instagram make my photos blurry?
Images larger than 1080px wide get aggressively compressed on upload. Resizing to exactly 1080px beforehand prevents automatic blurriness.
How do I post vertical photos to Stories without clipping?
Select the 9:16 Story preset and enable "Fit Canvas" — this creates a full 1080 × 1920 canvas so nothing gets cut off.
Are my photos uploaded to any server?
No. All processing happens locally in your browser using Canvas APIs — 100% private, always.
