About Image Info

Read width, height, aspect, megapixels, and MIME for any photo in seconds with this free image info analyzer. Drop a file for instant specs plus DPI hints instantly offline with no signup required ever, built for USA creators shipping precise assets Designed for USA startups, agencies, and enterprises needing fast reliable results without downloads or.

What specs the analyzer surfaces: Drop JPG, PNG, WebP, AVIF, or HEIC under 25 MB and get width, height, aspect ratio like 3 by 2 and 16 by 9, megapixels width times height divided by 1M, file size KB and MB, MIME, color depth, and orientation. It reads EXIF for dimensions and flags mismatch between file MIME and extension that breaks CDN in Austin and Chicago. For a 4000 by 3000 iPhone shot from Miami beach, you see 12 MP and 4 by 3, ideal for cropping to 1200 by 630 OG without stretch.

Why dimensions drive USA commerce and social: Shopify requires 2048 square for zoom on $49 to $299 products; Amazon wants 1600 on long edge white background. Facebook large cards need 1200 by 630, Instagram square 1080 by 1080, and X 1200 by 675 for Seattle to New York reach on 07/15/2026 drops. Wrong aspect crops logos or faces, costing CTR. Denver print needs 300 DPI: an 8 by 10 inch press needs 2400 by 3000 pixels. The analyzer flags undersized sources before you pay $45 press proof dated 06/20/2026.

File size, DPI, and responsive guidance: Web hero under 500 KB loads fast on Dallas LTE, but a 5 MB Austin raw slows LCP. Use analyzer file size plus megapixels to pick export: 0.5 MP for thumb 800 by 600, 2 MP for hero 1920 by 1080, 12 MP for print 4000 by 3000. DPI is metadata; true print size is pixels divided by DPI. A 3000 pixel width at 300 DPI prints 10 inches, at 150 DPI prints 20 inches softer. Seattle devs bucket srcset at 640, 1024, 1920, and 2560 to cover iPhone and 4K from Washington to Florida.

EXIF, orientation, and quick fixes: EXIF may store rotation 90 that browsers correct but email clients ignore, flipping Chicago headshots sideways. Analyzer shows decoded width after rotation. It counts missing alt context and suggests renaming with MM/DD/YYYY slug like denver-trail-07-10-2026.jpg for SEO. If aspect off, route to Image Resizer or Cropper, then re-analyze to confirm 16 by 9. For HEIC from iPhone 14 in Austin, convert to JPG before upload to Illinois CMS that still blocks HEIC on 08/01/2026.

Privacy, cost, and next tools: Parsing is local via FileReader and createImageBitmap, free instantly offline with no signup required ever, so unreleased New York campaign stills stay private. No $0.10 per image API fee. After specs, run Compressor for WebP, Background Remover for isolation, or DPI Calculator for print math. Keep one master 4000 pixels and derive dependents, tracking versions by 09/01/2026 archive for audits across Texas to Manhattan.

Where it is used

Austin photographers validating Texas gallery exports before 07/10/2026 print, Chicago editors checking Illinois OG 1200x630 for Facebook, Miami shops confirming Florida WebP sizes for Shopify under $199, Denver printers verifying Colorado DPI 300 for 10 by 8, Seattle devs auditing Washington responsive srcset buckets, and New York agencies vetting Manhattan hero crops across breakpoints Each scenario runs on current MM/DD/YYYY dated data 07/15/2026 with budgets from $49 to $499 and ships before the late summer deadline.

How to use the Image Info

  1. Select Image — select a file (image/*) — Any browser-decodable image up to 25 MB..
  2. Calculate — press the Calculate button to see the result instantly above.

Formula

Read file → create Image bitmap → width × height → aspect = w/h reduced, MP = w*h/1e6, size KB/MB, MIME from file type and EXIF.

Examples

iPhone 12 MP

image:IMG_1234.HEIC 4032x3024
Result: 4032x3024 4:3 12.2 MP HEIC 4.8 MB rotated 90 decoded to 3024x4032

OG check

image:og.jpg 1200x630
Result: 1200x630 1.91:1 0.76 MP JPG 182 KB — perfect large card

Print ready

image:poster.png 3000x2400
Result: 3000x2400 5:4 7.2 MP PNG 2.1 MB — prints 10x8 at 300 DPI

Frequently Asked Questions

Which formats are supported?
JPG, PNG, WebP, AVIF, GIF, SVG, HEIC under 25 MB. HEIC may need conversion for Illinois CMS compatibility.
Why show megapixels?
MP signals detail budget: 0.5 MP for thumbs, 2 MP for web hero 1920x1080, 12 MP for 4000x3000 press.
DPI versus pixels?
DPI is metadata. Print inches = pixels / DPI. 3000px at 300 DPI = 10 inches crisp for Denver 10x8.
Orientation looks wrong?
EXIF rotation may flip Chicago portraits. Analyzer shows decoded size after rotation; re-export to bake orientation.
Is analysis private?
Yes. Local FileReader only, free offline with no signup. Files never upload from browser.
After info, what next?
Route to Resizer for srcset, Compressor for WebP under 500 KB, or DPI calc for print math before 09/01/2026.
