How to Identify a Font from an Image
Whether you are inspecting a website screenshot, a packaging mockup, or a printed specimen, isolating clean letterforms is the key to accurate typeface identification.
Upload, Paste, or Load a URL
Drop a JPEG, PNG, or WebP file, press Ctrl+V anywhere on the page to paste a screenshot from your clipboard, or load a direct image link.
Isolate One Horizontal Line
Adjust the crop handles around a single line of 4 to 10 characters with clean contrast. Exclude neighboring lines, icons, or decorative borders.
Verify Diagnostic Letterforms
Type the exact text from your sample into the live preview input and compare up to two candidate fonts side by side before copying the CSS.
What to Look For When Comparing Candidate Fonts
Automated font finders narrow thousands of typefaces down to the closest structural candidates. Because many neo-grotesque sans-serifs and classic serifs share similar skeletons, typographers confirm the exact face by inspecting diagnostic glyphs in the specimen preview:
a · g · e
Lowercase Construction & Counters
Check whether lowercase 'a' and 'g' are double-storey or single-storey, whether the 'e' crossbar is level or tilted, and how open the apertures are.
G · Q · R · M
Uppercase Terminals & Tails
Inspect the spur and crossbar on 'G', where the tail of 'Q' intersects the bowl, the leg curvature of 'R', and whether 'M' has splayed or vertical outer strokes.
I · l · 1 · 0
Disambiguation & Figures
Compare serif bars on uppercase 'I', the top flag on '1', and whether numerals use tabular, proportional, or oldstyle heights.
x-height & Weight
Proportions & Stroke Contrast
Observe how tall lowercase letters sit relative to capitals, the ratio between thick and thin strokes, and whether terminals end in ball, teardrop, or flat cuts.
Best Image Inputs vs. Common Identification Limits
Image quality and source material determine whether you get an exact family match or a close visual alternative. Here is what works best and why certain lettering cannot be matched to a standard font file.
Ideal Samples for High Accuracy
- Uncompressed UI screenshots or web page captures at 100%+ zoom
- A single horizontal line containing 4 to 10 distinct characters
- Text height of at least 24–32 pixels in the cropped selection
- Solid dark text on a light background (or clean inverted text)
- Standard Latin, Cyrillic, or multi-script body and headline type
Why Exact Identification Isn't Always Possible
- Custom-drawn brand logotypes, bespoke lettering, or calligraphy
- Curved, arched, circular, or heavy 3D perspective-warped text
- Overlapping letters, heavy drop shadows, outlines, or gradient fills
- Blurry camera photos taken at an angle or below 16px character height
- Single isolated characters or symbols without surrounding word context
How On-Device Font Identification Works
Unlike legacy font finders that require uploading your images to a remote server and manually typing every character below segmented boxes, FontLeech runs a compact neural vision encoder directly in your browser via WebGPU (with automatic CPU fallback).
When you crop a line of text, the tool normalizes contrast and deskews the baseline into sliding grayscale windows, projects the visual style into a high-dimensional embedding vector, and computes similarity against pre-indexed style vectors across Google Fonts, DaFont, Font Library, and WhatFontIs—detecting both the typeface family and its closest weight and italic posture.

Frequently Asked Questions
How do I identify a font from an image or screenshot?
Upload an image file (JPEG, PNG, or WebP), press Ctrl+V (or Cmd+V) to paste a screenshot directly from your clipboard, or load an image URL. Drag the crop box tightly around a single horizontal line of 4 to 8 clear letters, then click Identify Font. Type the exact word from your image into the specimen preview box to compare letterforms side by side.
Are my uploaded images sent to a server?
No. File uploads and clipboard pastes are processed entirely inside your web browser using WebGPU or your device's CPU. Your images never leave your device. If you paste an external image URL, FontLeech retrieves that image once so your browser can read its pixels without cross-origin errors, and all font analysis still runs locally.
Which font catalogs does FontLeech search?
The identifier compares your cropped text against more than 100,000 indexed typeface families across Google Fonts (including individual weights and italic styles), DaFont, Font Library, and the WhatFontIs benchmark catalog.
Why does the tool show visually similar fonts instead of a single 100% match?
In digital typography, many typefaces share nearly identical proportions—especially geometric sans-serifs, neo-grotesques, and classic Garalde serifs—and rasterized images lose sub-pixel curve data. Rather than fabricating a misleading probability percentage, FontLeech ranks the closest visual matches so you can verify diagnostic characters (like 'G', 'Q', 'R', 'a', and 'g') using live text previews.
Why couldn't the tool find an exact match for a logo or poster?
Corporate logos, mastheads, and movie titles frequently use custom-drawn wordmarks, modified commercial foundry releases, or hand-lettered scripts that do not exist as public font files. In those cases, the identifier surfaces the closest available free and catalog alternatives.
Can I get the CSS code once I find the right font?
Yes. Every result card includes a one-click Copy CSS button that generates the ready-to-use font-family stack, matched font-weight and font-style declarations, and the Google Fonts @import rule when available.
