Resize Image for Instagram Post (1080x1350) — Free Online Tool
Instagram displays feed posts at 1080 pixels wide, and the 4:5 portrait ratio (1080x1350) gives you the maximum vertical real estate in the feed. This matters because taller posts occupy more screen space as users scroll, increasing the chance they stop and engage with your content. Square posts (1080x1080) take up less room, and landscape posts (1080x608) even less — so portrait is the format most creators and marketers prefer for maximum visibility.
Why Resize for Instagram?
Instagram compresses every image it receives, so starting with the right dimensions minimizes double-compression artifacts. When you upload a 4000x3000 photo, Instagram first resizes it to fit its grid, then compresses it — two rounds of quality loss. Uploading at exactly 1080x1350 means Instagram only needs to compress once, preserving noticeably more detail. The 4:5 portrait orientation is strategically valuable for engagement. Studies consistently show that taller posts receive higher engagement rates because they dominate more of the mobile screen. When a user is scrolling through their feed, a portrait post fills roughly 30% more screen area than a square post and nearly double a landscape post. That extra visual presence translates directly to more likes, comments, and saves. Privacy is another key advantage of resizing with our tool. Every photo from your phone contains hidden metadata — GPS coordinates accurate to a few meters, your device model and serial number, the exact date and time, and even which direction you were facing. Stripping this data before posting protects your privacy without any extra steps. Our tool removes all EXIF, XMP, and IPTC metadata automatically during the resize process. Because the tool runs 100% in the browser, it works on any device — iPhone, Android, laptop, or desktop — without installing apps or creating accounts. Free users can resize up to 10 images per day, and Pro subscribers ($10/month) get unlimited daily usage.
How It Works
Drop your image onto the page or tap to select it from your camera roll. The tool loads the image using your browser's Canvas API — no server upload occurs. You'll see a live preview showing how your image will look at 1080x1350. Use the crop handles to adjust which portion of the image fills the frame, or choose "fit" mode to include the entire image with letterboxing. Select your preferred output format (JPEG, PNG, or WebP) and adjust the quality slider. For Instagram, JPEG at 85-92% quality provides the best balance — sharp enough for detailed images but compressed enough that Instagram's own compression doesn't degrade it further. The tool calculates the output file size in real-time so you can dial in exactly what you need. Click "Download" and the resized image is saved directly to your device. All EXIF metadata — GPS, camera info, timestamps — is stripped automatically. The file is ready to upload to Instagram immediately.

Frequently Asked Questions
What is the best image size for Instagram posts?
1080x1350 pixels (4:5 portrait) is the optimal size. It gives you the maximum vertical real estate in the feed, increasing engagement. Instagram supports widths from 320 to 1080 pixels, but always upload at 1080px wide for the sharpest result.
What happens if I upload a different size to Instagram?
Instagram will auto-resize and crop your image to fit. Photos wider than 1080px get downscaled, and non-standard aspect ratios get cropped to the nearest supported ratio (1:1, 4:5, or 1.91:1). This often cuts off important parts of your image and adds extra compression, reducing quality.
Should I use JPEG or PNG for Instagram posts?
JPEG at 85-92% quality is best for Instagram. Instagram converts everything to JPEG internally anyway, so uploading a large PNG just means Instagram has to do more compression, often with worse results. A well-optimized JPEG gives Instagram the least work to do.
Does Instagram strip metadata from my photos?
Instagram does strip most EXIF data during upload, but your original file still contains it until then. If you share the original file elsewhere (email, messaging apps), the metadata is exposed. Our tool strips metadata before you upload, protecting you across all sharing methods.
Can I resize multiple photos for Instagram at once?
Yes. Free users can process up to 5 images per batch, and Pro users up to 10. All images are resized to 1080x1350 and can be downloaded individually or as a ZIP archive — perfect for preparing carousel posts.
Is this tool free to use?
Yes. Anonymous users get 5 free uses per day, logged-in users get 10 per day, and Pro subscribers ($10/month) get unlimited usage. No credit card is required for the free tier.
Does resizing reduce image quality?
If your original image is larger than 1080x1350, the downscale preserves excellent quality — you won't notice any difference. If your original is smaller, the image will be upscaled, which can introduce softness. For best results, start with images at least 1080 pixels wide.
