Resize images for Instagram

Every Instagram size at once — portrait, square, landscape, story — previewed live so you see exactly what gets cropped before you download.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the Instagram Image Resizer

  1. Drop one image — a photo, logo or design export.
  2. Every size for this platform appears as a live preview with its dimensions and ratio.
  3. Slide between Fit and Fill on any card and drag the preview to reposition; nothing is stretched.
  4. Download a single size, or all of them as a ZIP.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

Instagram displays feed images at up to 1080 px wide and gives 4:5 portrait posts (1080×1350) the most screen space; squares (1080×1080) still work, landscape posts are 1080×566, and stories and Reels are full-screen 9:16 (1080×1920). Uploading at exactly these sizes means Instagram recompresses far less than when it has to shrink a 4000 px photo itself. For stories, keep text out of the top and bottom 250 px where the username and reply bar sit.

Every Instagram size on this page, verified for 2026: Story / Reel cover 1080×1920 px (9:16 · up to 30 MB), Portrait post 1080×1350 px (4:5 · recommended), Square post 1080×1080 px (1:1), Landscape post 1080×566 px (1.91:1), Carousel 1080×1350 px (4:5 · up to 20 slides), Profile photo 320×320 px (1:1 · shown as a circle). Each card is a live preview of your image in that frame — drag to reposition, slide between Fit (whole image, background added) and Fill (frame covered, edges cropped), then download the one you need or every size as a ZIP. Nothing is uploaded; the rendering runs in your browser.

Export as JPG at quality 85–90 — Instagram converts everything to JPEG anyway, and a correctly sized, cleanly encoded file gives the sharpest result. If a photo is very different in shape from 4:5, use Fit with a white or coloured background instead of Fill so nothing important is cropped.

This is a pre-set view of the Social Media Image Resizer. Every other platform is one tab away.

Frequently asked questions

What size should Instagram posts be in 2026?

1080 px wide. Portrait posts are 1080×1350 (4:5), squares 1080×1080, landscape 1080×566. Stories and Reels are 1080×1920 (9:16). Instagram downsizes anything wider to 1080, so uploading larger only invites extra compression.

JPG or PNG for Instagram?

JPG at quality 85–90. Instagram re-encodes uploads as JPEG; a PNG is larger to upload and gains nothing. Keep colours in sRGB.

Will my photo be cropped?

Only if you choose Fill. Each card has a slider: Fit shows the whole photo with a background colour, Fill covers the frame and trims the edges — and you can drag the preview to decide which part is kept. Nothing is ever stretched.

What size is a Instagram story / reel cover in 2026?

1080×1920 pixels (9:16), under 30 MB — 9:16 · up to 30 MB. Drop your image above and the story / reel cover card renders it at exactly that size; use the Fit/Fill slider to choose between showing the whole picture and filling the frame.

What size is a Instagram portrait post in 2026?

1080×1350 pixels (4:5) — 4:5 · recommended. Drop your image above and the portrait post card renders it at exactly that size; use the Fit/Fill slider to choose between showing the whole picture and filling the frame.

Other presets

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
