Your file stays in your browser
The SVG checker reads the file you select in the current page. It does not upload it, send it to another service, or keep a copy. Closing or reloading the page clears the selected file and result. Exported reports are saved only when you choose to download them.
Calculations and storage
Your size-tool inputs remain in the current page. When you follow a file’s sizing link, the selected file name, dimensions, unit and groups are kept in your browser for a moment so the sizing page can read them. They are not added to network request URLs. We do not retain a profile of your measurements.
Analytics and cookie choices
We use two measurement services to see which pages and tools people use: Plausible Analytics (Plausible Insights OÜ, European Union) and Google Analytics 4 (Google LLC, United States). They receive page-view information and a small set of named actions, such as checking an SVG, filtering or ordering the library, running a size calculation or downloading a file.
Plausible counts every visit without cookies. It may receive browser and device information and a referring page.
Google Analytics is run by Google, which receives the page address, the actions we measure on this site and browser and device information, and sets cookies that tell repeat visits apart. Its advertising features are off.
In the European Union, Iceland, Liechtenstein, Norway, the United Kingdom and Switzerland, and whenever we cannot tell which country a visit comes from, Google Analytics loads only after you choose Accept on the bar at the bottom of the page. Decline loads nothing from Google. Your choice is kept in this browser for six months, then the bar asks again.
Elsewhere, Google Analytics loads with each page unless you choose Decline. Cloudflare, which delivers our pages, tells your browser which country the visit comes from.
Wherever you are, Cookie choices at the bottom of any page, or the button below, changes your choice. Decline stops Google Analytics on this site in this browser and deletes its analytics cookies. If analytics was running, the page reloads to apply your choice. Decline holds on every page; outside the countries above it is kept until you change it.
Plausible measures visits without cookies and without any identifier that follows you between sites. It also receives the referring page address when your browser provides one.
The file you check, its contents, its name, your measurements and any text you enter are never included in what we send.
Who else receives data, and why
Google LLC (Google Analytics 4) for page and action measurement. Google's privacy policy is at policies.google.com/privacy.
Plausible Insights OÜ for cookie-free page measurement, hosted in the European Union.
Cloudflare, Inc. for the contact form: it carries the messages you send, runs the form’s automatic security check and keeps each message in our contact inbox for 12 months. A copy of each message goes to a private Discord channel (Discord Inc.) our team reads.
Nobody else. This site serves no advertising, carries no affiliate link and embeds no social widget. The only scripts it loads from elsewhere are the two measurement scripts named above and, on the contact page, Cloudflare’s security check; every font, SVG, preview and download comes from this site's own server.
If a display advertising network is ever added here, this page will name it and describe what it receives before the first advertisement is served.
If you are in the EEA or the UK
We do not sell or share personal information, and we run no profiling or automated decision-making.
You can ask what we hold, ask for it to be corrected or deleted, or object to measurement through our contact form. You can also stop measurement yourself: blocking Google Analytics and Plausible in your browser stops both, and every page, tool and download works without them.
Google deletes user-level and event-level measurement data when the retention period set in our Analytics property ends; for a standard property Google offers 2 or 14 months. That setting does not apply to Google's standard aggregated reports. Plausible keeps its counts in aggregate form without an expiry. The files you download are yours and we keep no record of which ones you took.
Contact
The contact form sends your message, your reply address, your name if you give one and any page or source you add through Cloudflare, which runs an automatic security check that never asks you to solve anything. We keep each message in our contact inbox at Cloudflare for 12 months, then it is deleted automatically, and a copy goes to a private Discord channel our team reads. We use your reply address only to answer you. To see or delete a message you sent, use the same form and we will delete both copies. Please do not include passwords, keys or private documents.
