Image to Base64
Encode a local image file as a Base64 data URL for embedding in HTML or CSS.
Data URLs embed file bytes directly in markup—useful for tiny icons, email templates, or quick prototypes. Choose a file in the browser; the result never leaves your machine. Very large images blow up page size—prefer URLs or CDNs for big assets.

FAQs
When should I use Base64 images?›
For very small assets where an extra HTTP request hurts more than a larger HTML payload. Avoid for large photos.
What about caching?›
Inline Base64 bypasses separate cache entries for that image; linked files cache normally.
Is there a size limit?›
The browser tab’s memory is the limit. Huge files may hang or crash—resize first.
General
Do these tools send my data to Exemplar’s servers?›
By default, conversion and formatting run entirely in your browser. Nothing is uploaded to Exemplar for normal paste-and-transform workflows. Tools that deliberately open an external service (for example, a third-party speed test) are called out on the page.
Do I need an account or install anything?›
No account is required. Everything runs in the browser—there is nothing to install for these utilities. They complement the Exemplar platform but work standalone.
Are these utilities open-source or the same as other sites?›
These pages are built for Exemplar’s audience (developers working with APIs, config, and ops data). Behavior may differ slightly from other online tools; always verify critical output in your own environment.
Are there size or performance limits?›
Very large inputs can slow down or crash the tab—especially for images, huge JSON, or multi‑MB HAR files. For production-scale data, prefer local CLI tools, streaming parsers, or your own pipelines.
Can I use output in production?›
Yes, when you have validated it. Parsers and formatters here aim to be helpful for everyday tasks but are not a substitute for tests, schema validation, or security review where it matters.
