Common screenshot pitfalls, solved
Building your own screenshot solution? These issues probably look familiar.
The problem: Ads and cookie banners clutter screenshots and cover the content.
With Snapi: Ads and common cookie banners are removed automatically for clean screenshots.
The problem: Chinese, Japanese, and Emoji show up as empty boxes.
With Snapi: Chinese, Japanese, Korean, and Emoji render correctly, just like in your browser.
The problem: The bottom half of your full-page screenshot is blank, with lazy-loaded images missing.
With Snapi: Full-page screenshots capture lazy-loaded images, so long pages don't end up half-empty.
The problem: Your screenshot of a single-page app shows nothing but a loading spinner.
With Snapi: Snapi intelligently waits for the page to render, or you can tell it to wait for a specific element.
The problem: Your DIY screenshot service is hard to maintain and unreliable under heavy traffic.
With Snapi: No infrastructure to build or maintain. Just call the API.
The problem: You get charged for failed requests and repeated captures of the same page.
With Snapi: Only successful requests are billed. Failed requests and cache hits don't use your credits.
Chinese web pages, finally captured right
Many screenshot tools turn Chinese text into empty boxes. Snapi captures it just as you see it in your browser.

Everything you need in a screenshot API
Every parameter has a sensible default, so you get a clean screenshot without extra configuration.
Chinese text without missing glyphs
Simplified Chinese, Traditional Chinese, Japanese, Korean, and Emoji render correctly—even when mixed together. No missing-glyph boxes.
Full-page or element screenshots
Capture entire long pages, including images that load on scroll, or capture just one element.
Web pages to PDF
A4 / Letter, with background colors and images preserved. Supports both print and screen styles.
Signed URLs
Embed screenshot links directly in your pages without exposing your key. Any change to the link invalidates it.
Near-instant repeat requests
Identical requests return almost instantly and don't count against your quota.
Block ads and pop-ups
Automatically remove ads, tracking scripts, and cookie consent banners for cleaner screenshots and faster captures.
Secure isolation
Each capture runs in isolation, keeping your page content private. Unsafe addresses are blocked automatically.
Pay only for success
Timeouts, unreachable pages, and target site errors don't count against your quota. If a request fails, you'll know why.
Use your favorite language. Integrate in five minutes.
A standard HTTP interface—no SDK required. Errors return consistent JSON with a clear reason and request ID, making troubleshooting straightforward.

- 03
Get your image or PDF

Good questions. Clear answers.
Why does Chinese text appear as boxes in screenshots? Will that happen with Snapi?
No. Many screenshot tools turn Chinese text into boxes. Snapi is built to solve this: Simplified Chinese, Traditional Chinese, Japanese, Korean, and Emoji all render correctly, just as they appear in your browser.
Which requests count against my quota?
Only successfully rendered requests count: each screenshot uses 1 credit, and each PDF uses 2 credits. Cache hits, timeouts, rendering failures, target site errors, and invalid parameters don't count.
Can I embed screenshot links directly in my web pages?
Yes, with signed URLs. Generate a signature on your server using your secret, then put the signed URL in <img src>. Your secret never appears in the page, and changing any parameter invalidates the signature.
Can I capture pages that require a login?
Currently, you can capture public pages and HTML you submit directly. Support for custom request headers, cookies, and user agents is in development.
What are the free plan limits?
100 requests per month, up to 2 requests per second and 2 concurrent requests. Once you use your monthly quota, requests are blocked until it resets. Paid plans are coming soon.
