If html2canvas crops or offsets text after a CSS rotation, first test whether overflow clipping and the transform interact: temporarily make overflow visible, then separately remove the transform, recapturing after each change. A user report in html2canvas issue #3277 proposes that clipping bounds may be measured before a transform is applied, but that is an unconfirmed diagnosis—not a released fix. Isolate the failure before changing application styles or the renderer.
What the rotated-text report does—and does not—establish
The report titled “Bug in html2canvas – rotated text fields” describes “a cropping of the rotated text.” Its author suggests that a ClipEffect is created from border-box or padding-box curves measured without the transform, and proposes not creating that clipping effect when the element or a parent has a CSS transform. As of September 29, 2026, the report was open and the viewed page showed no associated pull request. That proposal is a useful debugging lead, not a maintainer-confirmed root cause or a drop-in patch.
Keep three failure types distinct while investigating: text that is clipped, text that is in the wrong position or orientation, and text whose glyphs or value render incorrectly. A crop that changes when overflow is toggled points toward clipping; a position change when the transform is toggled suggests a different part of the rendering path. These observations narrow the problem, but do not prove which internal step is responsible.

Build a small reproduction before patching
Start with the smallest element that still shows the problem. Record the exact html2canvas package version, browser and version, operating system if relevant, capture target, and whether the affected content is ordinary DOM text or an input/control value. Note the computed transform, transform-origin, width, height, and overflow on the rotated element and every ancestor. Also record any scrolling or clipping container and the capture bounds.
Here is a minimal page to adapt. Install html2canvas in the project with npm install html2canvas, save the markup as an HTML file served by your local development server, and adjust the element’s styles until the discrepancy appears. The button captures the target element and displays the resulting canvas. Compare that output with a native browser screenshot of the same page at the same viewport size.
<div class="frame">
<div id="capture-target">
<span class="rotated-label">Quarterly report</span>
</div>
</div>
<button id="capture">Capture element</button>
<div id="result"></div>
<style>
.frame {
width: 320px;
height: 180px;
overflow: hidden;
border: 1px solid #777;
}
#capture-target {
width: 300px;
height: 150px;
overflow: hidden;
padding: 12px;
}
.rotated-label {
display: inline-block;
transform: rotate(-18deg);
transform-origin: left top;
font: 24px sans-serif;
}
</style>
<script type="module">
import html2canvas from "html2canvas";
const target = document.querySelector("#capture-target");
document.querySelector("#capture").addEventListener("click", async () => {
const canvas = await html2canvas(target);
const result = document.querySelector("#result");
result.replaceChildren(canvas);
});
</script>If your build setup does not resolve bare module imports in browser-served HTML, run the reproduction through the same bundler or module setup used by your application. Keep that setup, package version, and browser consistent between the baseline and each test; otherwise a changed result may have more than one explanation.

Isolate overflow, transform, and capture bounds
Change one variable per capture and keep a short record of the result. First reproduce the original output, then test these cases independently:
| Test | What to change | What the result tells you |
|---|---|---|
| Overflow | Set overflow to visible on the rotated element, then on each clipping ancestor in turn. | If the crop disappears only when a particular overflow rule is relaxed, clipping is implicated. Note any additional content now visible. |
| Transform | Remove the transform while leaving dimensions and overflow unchanged; restore it before the next test. | A changed crop or position shows the failure depends on the transform, but does not establish whether the transform, its origin, or clipping calculations are at fault. |
| Capture boundary | Capture a larger wrapper with enough room around the transformed text. | If the text is no longer cut off, the capture boundary may be too tight. Check whether unrelated surrounding content has entered the output. |
| Content type | Compare ordinary DOM text with the affected input or control value, if relevant. | If only a control is affected, report that distinction; an input-rendering problem is not automatically the same as a DOM-text clipping problem. |
| Environment | Repeat the unchanged case in another browser and record both versions. | This helps establish whether the behavior is environment-specific. The project’s getting-started page lists Chrome/Chromium-based browsers, Firefox, and Safari among supported modern evergreen browsers; report the exact versions you tested. |
For the overflow test, inspect the whole ancestor chain, not just the text node. A clipping container outside the element you pass to html2canvas can matter to the visible result. Also keep the viewport, scroll position, and requested capture target stable. If the element extends beyond the target’s bounds, distinguish that boundary crop from clipping caused by CSS overflow.
Try a narrowly scoped workaround
If making overflow visible resolves the crop, a practical temporary workaround is to apply that change only to a cloned document used for capture, or to capture a wrapper whose layout provides enough space and whose overflow is visible. Verify the resulting layout in every target browser: visible overflow can reveal neighboring content, alter what enters the captured region, or fail to address the issue if another ancestor still clips it.

html2canvas provides configuration for ignored elements, viewport dimensions, and callbacks that can copy or adjust styles in the cloned document. Those controls can help you scope a reproduction or workaround, but their existence does not establish that they fix transformed-text clipping. If you adjust cloned styles, target only the relevant element or ancestor and compare the cloned capture with the unmodified baseline.

Do not copy the issue author’s suggested styles.transform === null condition into production as if it were an upstream fix. The report remains unconfirmed, and broadly suppressing clipping for every transformed element could change intended behavior elsewhere. Avoid a global CSS change until the minimal reproduction shows that it addresses your specific crop without introducing layout regressions.
Why Canvas support does not guarantee an html2canvas fix
Canvas 2D can paint text under a transformation. The WHATWG Canvas standard says the current transformation matrix is applied when painting text, shapes, and Path2D objects. That establishes that transformed text is possible on a canvas; it does not guarantee that html2canvas reconstructs every browser CSS transform, transform origin, measurement, and clipping interaction exactly.

The important distinction is between Canvas’s ability to transform painted text and html2canvas’s work of interpreting DOM styles, computing bounds, applying clipping, and painting the result. The official html2canvas FAQ says: “Every CSS property must be manually implemented to render correctly, so html2canvas will never have full CSS support.” It recommends creating a test case and opening an issue when a property is missing or incomplete.
Keep related transform reports separate
html2canvas pull request #3153 concerns an input/image error involving transform: translateX(15%) rotate(-12deg);. The viewed pull request was still open in the main repository; a commenter said the change had been merged into html2canvas-pro. That is related evidence that transform handling has prompted other reports, but it does not show that the change fixes issue #3277 or rotated-text cropping. Do not apply or cite it as the solution to a different reproduction without verifying the match.
Troubleshoot the common failure patterns
- The text is still cropped after setting the text element to overflow: visible. Check each ancestor for overflow clipping, then test a larger capture wrapper. The clipping rule or capture boundary may be elsewhere in the chain.
- Removing the transform fixes the crop, but overflow changes do not. Record the transform and origin, then reduce the reproduction further. That result makes transform handling a lead, not proof of the issue author’s proposed ClipEffect diagnosis.
- The canvas has the right text but at the wrong location. Treat this as an offset or bounds problem rather than describing it only as clipping. Include element dimensions, transform origin, ancestor styles, and capture bounds in the report.
- Only an input or other control value fails. State the exact control type and compare it with ordinary text. The separate input/image report in pull request #3153 should not be treated as confirmation that the same cause applies.
- The local style workaround changes too much of the page. Narrow it to the cloned capture document and the relevant element or ancestor, or enlarge the capture wrapper instead. Recheck what extra content becomes visible.
- You cannot reproduce it consistently. Fix the browser version, viewport, scroll position, package version, and styles, then repeat the baseline before testing changes. A reproduction with multiple uncontrolled differences cannot isolate the cause.
File a focused upstream issue if it remains reproducible
