SVG recommended — stays crisp at every size, including 12 px
// How it works
Three steps. Zero friction.
No accounts, no uploads to a server, no plugins. Just drop your logo and get the answers you need in seconds.
Upload your logo
Drag and drop — or click to browse — your SVG, PNG, JPG, or WebP file. Files are read in your browser and are not uploaded to our server. For best results, use an SVG so every size stays crisp and vector-sharp.
Preview all 10 sizes at once
The tool renders your logo simultaneously at Hero (800 px), Website Nav, Email Signature, Social Avatar, WhatsApp DP, Business Card, App Icon, Touch Icon, Favicon, and Footnote sizes. Switch between light, dark, and transparent backgrounds to spot contrast issues instantly.
Download the scale audit PNG
Hit the Download button to generate a 1200 × 1600 px audit sheet showing all sizes in a single portfolio-ready image. Share it with clients, attach it to a brand guidelines deck, or post it as a case study on social media.
Why logo scale testing matters before you deliver
A logo that looks stunning at 600 px in Figma can completely fall apart at 16 px as a browser favicon. Thin strokes disappear. Letterforms blur together. Negative space collapses. These aren't edge cases — they're the standard real-world sizes every brand identity lives at.
Logo scale testing used to require a designer to manually place the logo at each target size inside Figma, a PDF, or Illustrator, then export screenshots one by one. The Logo Scale Tester replaces that entire workflow with a single browser tab: upload once, see every size instantly, export a shareable audit sheet.
The tool renders SVG logos inline — which means they stay mathematically perfect at any size, the same way a browser renders them in production. Raster formats (PNG, JPG) are rendered via the native Canvas API at exact pixel dimensions, so what you see in the tool is exactly what users will see in the wild.

Frequently asked questions
Is the Logo Scale Tester completely free?
Yes — all features including the scale audit PNG export are free with no account required. There are no tiers, no watermarks, and no paywalls.
Does my logo get uploaded to your server?
The tool reads and renders your logo locally and does not upload the file or audit PNG to our server. Inline SVGs may include external resource references that trigger browser requests; the sanitizer does not strip every external reference. Site analytics, ads and page-resource requests are separate from logo processing.
What file types are supported?
SVG, PNG, JPG, and WebP files up to 5 MB. SVG is strongly recommended because it renders crisply at all sizes including 12 px and 16 px. PNG also works well for logos with transparency.
Why does my SVG look blurry at small sizes?
SVG itself never blurs — it's vector. If your logo looks unclear at 12–16 px it means the design has fine detail that physically cannot render at that scale. This is the entire point of the tool: to discover these issues before production.
What is the scale audit PNG export?
The Download button generates a 1200 × 1600 px portrait PNG showing all size variants on one page, labeled by use case. Designers use this to present logo scale testing to clients or to post on social media.
Which sizes are tested?
10 standard real-world sizes: Hero/Web Header (800px), Website Nav (200px), Email Signature (150px), Social Avatar (128px), WhatsApp DP (96px), Business Card (60px), App Icon (48px), Touch Icon (32px), Favicon (16px), and Footnote/Watermark (12px).

How it works, data handling & limitations
- How it works
- FileReader loads your logo locally. Sanitized SVG or raster images render at ten sizes against different backgrounds; a browser canvas creates the PNG audit sheet.
- Data & privacy
- The tool does not send your logo or generated audit sheet to our server or store it in a tool database. File processing stays in the browser, but inline SVGs can contain external resource references that trigger requests; the sanitizer does not remove every external reference. Site analytics, ads and browser requests for page resources still apply.
- How we evaluate/test it
- Source review confirms local file handling and the configured size previews. No automated visual regression suite or physical print-validation programme was found.
- Limitations
- Screen previews are not a substitute for physical print proofs. Raster resolution, embedded SVG content and display pixel density can affect appearance. A scale sheet is a visual aid, not a pass/fail certification.
Use the contact form to report a bug, an incorrect result or a privacy concern. Include the tool name and result link when available.
Changelog
- Replaced an absolute "nothing is ever sent" claim with what actually stays local.
- Added author, methodology, data handling, limitations and maintenance information.
