Google rewrites most descriptions. Studies consistently find it replaces the supplied meta description for the majority of results, usually with a passage from the page that better matches the query. Yours is the version you control, not the version that will always show, which is an argument for writing the page well, not just the tag.

Reembun. (2026, July 28). SERP snippet preview. https://reembun.com/serp-snippet-preview
How to use it
Enter the page details
Page title, meta description and URL, exactly as they would be published.
Switch between devices
Mobile and desktop cut at different points, so a snippet that fits one can still be trimmed on the other.
Watch the width, not the character count
The preview measures pixels, which is how Google actually decides where to truncate. A title full of capitals runs out of room sooner.
Rewrite until the important part survives
Get the words that earn the click in before the cut off, and treat everything after it as a bonus.
Pixels, not characters
Google truncates snippets at a rendered width. Character counts are a proxy, and a poor one, because the same count occupies very different widths depending on the characters.
WWWWWWWWWWWWWWWWWWWW 20 characters, very wide
iiiiiiiiiiiiiiiiiiii 20 characters, very narrowThis preview measures rendered width rather than counting characters, which is why a title of 58 characters can show as truncated while one of 64 does not.
Approximate limits
| Element | Desktop | Mobile |
|---|---|---|
| Title | ~580 px (≈60 chars) | ~460 px (≈50 chars) |
| Description | ~920 px (≈155 chars) | ~680 px (≈120 chars) |
Google adjusts these periodically without announcement, so treat them as current guidance rather than a specification.
Front-load what matters
Since truncation removes the end, the words that must survive belong at the front.

Better: Compress PDF to Reduce File Size Without Losing QualityThe second reaches the point immediately, fits comfortably, and reads as an answer rather than an introduction.
Titles that work
Put the primary term first. It is what someone scanning results is looking for.
Include the brand only if it helps. A recognised brand earns clicks; an unknown one spends characters. Google frequently strips or rewrites a brand suffix anyway.
Avoid repeating words. “PDF Compressor: Compress PDF Files, PDF Compression” wastes width and reads as spam.
Match the query’s intent, not just its words. Someone searching “compress pdf” wants a tool, not an article about compression.
Descriptions that earn clicks
The meta description is not a ranking factor. It is advertising copy for a listing, and its job is to win the click over the nine other results on the page.
- Say what the page gives them, specifically
- Include a differentiator: “no upload”, “no sign-up”, “free”
- Write in active voice
- Do not simply restate the title
Google rewrites most descriptions
Multiple large-scale studies have found Google substitutes its own snippet for the majority of results, usually pulling a passage from the page that matches the specific query more closely.
That does not make the tag pointless. It is the default, it is what shows when the query matches your framing, and it is the only part you directly control. It does mean the page body matters more than the tag, since a well-structured page gives Google good material to pull from.
What the preview cannot show
Rich results, sitelinks, star ratings, images, dates and the many other enhancements Google may add depend on structured data, site authority, query intent and Google’s own judgement in the moment. The same page shows different treatments for different queries, and none of it can be predicted from a title and description.
Common questions
Why measure pixels instead of characters?
Because Google truncates by rendered width. A title of 60 capital letters is far wider than 60 lowercase ones, so a character count is only a rough proxy. This tool measures the actual rendered width instead, which predicts truncation much more reliably.
What are the real limits?
Roughly 580 pixels for a desktop title and 920 for a description; less on mobile. In characters that works out around 60 and 155 respectively for typical mixed-case text, but a title full of wide characters truncates sooner and one of narrow characters later.
Google rewrote my description. Why?
It does that for the majority of results, usually substituting a passage from the page that better matches the specific query. Your description is the version you control and the default it starts from, which is an argument for writing the page well, not just the tag.
Does the preview show rich results?
No. This shows the standard text snippet. Star ratings, sitelinks, FAQ blocks and other enhancements depend on structured data, query intent and Google's own judgement, and none of them can be predicted from a title and description alone.
