Base64 SVG decoder
Decode Base64 into a downloadable SVG file
This Base64 to SVG tool is built for users who have copied an encoded SVG string from HTML, CSS, an app export, a data URL, or a design file and need to turn it back into a normal `.svg` file as an SVG file.
Paste a Base64 SVG, an SVG data URL, or raw SVG markup. The tool decodes the content, removes unsafe or unnecessary parts when selected, normalizes sizing, previews the design, and lets you download a clean SVG file.
What this Base64 to SVG tool is for
This page decodes Base64 SVG strings and data:image/svg+xml URLs into readable SVG markup. Use it when you need to inspect what an encoded icon, CSS background, or embedded SVG really contains.
If the decoded payload is not SVG, the tool reports what it found and only uses raster tracing for supported image data. Malformed or unsafe input should be reviewed before export.
How to convert Base64 to SVG
Paste, decode, clean, preview, download SVG- 1Paste your Base64 SVGPaste a data:image/svg+xml;base64 URL, a plain Base64 SVG string, or raw SVG markup.
- 2Choose a cleanup presetUse clean SVG for most files, single-color SVG for simple icons, or strict clean SVG when you want to remove embedded raster images.
- 3Review the SVG checksCheck whether the SVG contains paths, text, scripts, metadata, or raster images before uploading it to an SVG editor.
- 4Adjust cleanup settingsPreserve colors, force a single color, remove scripts, remove metadata, normalize viewBox, or add a preview background.
- 5Download the SVGDownload the decoded SVG file, copy the SVG code, or export a CSV report with the detected file details.
Base64 SVG settings explained
Base64 decoding is only the first step. The decoded SVG may still contain scripts, metadata, embedded images, live text, missing viewBox values, or sizing attributes that are awkward in SVG an SVG editor.
Keeps the SVG as close as possible to the decoded source. Best for printable, mixed, or multi-color artwork.
Turns shapes into one solid color, which is useful for basic one-color SVG files.
Shows paths as outlines so you can inspect the outline before downloading.
Deletes embedded image tags from the SVG. Use this when you want cleaner vector-only output.
Adds a usable viewBox when possible, making preview and scaling more predictable.
Removes fixed width and height attributes so the SVG scales better in previews and web layouts.
Common Base64 to SVG problems and fixes
If the decoded content is PNG, JPG, JPEG, or WEBP image data, the tool can trace supported raster inputs into SVG paths instead of pretending the payload was SVG.
It may contain text, shapes, symbols, or embedded images instead of path elements. Editor behavior may vary.
The SVG contains live text. Install the same font or convert text to outlines before final use.
Try adding a solid background, preserving colors, or disabling strict raster removal.
Keep embedded images for mixed artwork, or remove them for cleaner vector-only SVG output.
Make sure the string is complete and does not include extra quotes, CSS wrappers, or broken characters.
Backend conversion usage limits
Client-side actions on this Base64 to SVG conversion page are not rate limited. Plain Base64 SVG decoding, SVG cleanup, preview updates, copy, CSV export, and print-to-PDF run in the browser after the page loads, so they do not use server conversion compute.
Rate limits apply only when the input is a Base64 PNG, JPG, JPEG, or WEBP image that needs backend raster tracing into SVG paths. That server-side conversion allows up to 120 conversions per minute, 400 conversions every 5 minutes, 1500 conversions per hour, and 3000 conversions per day for the same IP address and browser profile. If a limit is reached, the server returns a 429 Too Many Requests response with a Retry-After value.
Base64 workflow
Base64 to SVG Decoder: practical workflow notes
Decode Base64 or SVG data URLs back into SVG source you can preview, copy, and download. Use this page when that specific output is the fastest path, then jump to the related tools below if you need a different export, cleanup, or craft-file workflow.
Best for
- base64 to svg
- SVG data URLs, CSS embeds, HTML snippets, and encoded SVG strings
- Debugging Base64 output before using it in production
- Copy-ready Base64 or decoded SVG source
Settings to try
- Choose Base64-only or data URI output based on where the result will be pasted.
- Keep sanitization enabled when decoding unknown SVG data.
- Use copy actions for code snippets and download actions for reusable files.
Useful limits
- Base64 tools encode or decode SVG data; they are not raster tracing pages.
- Very large encoded assets can be awkward in CSS or HTML.
- Sanitization can remove unsafe scripts or event handlers from decoded SVG.

Frequently asked questions
Can I convert Base64 to SVG?
Yes. If the Base64 content is encoded SVG, this tool decodes it, cleans it, previews it, and lets you download a normal SVG file.
What if the Base64 is PNG or JPG instead of SVG?
If the input is supported raster image data, the tool can trace it into SVG paths. The primary workflow is still decoding and inspecting Base64 SVG data.
What input formats does this accept?
It accepts raw SVG markup, SVG data URLs, Base64-encoded SVG strings, and supported Base64 raster image data URLs for tracing when the payload is not SVG.
Why does the font change?
If the decoded SVG contains live text, SVG may substitute the font. Use installed fonts or convert text to outlines before final use.
Should I remove embedded raster images?
Remove them for cleaner vector-only SVG output. Keep them if your project needs embedded bitmap artwork.
Is the decoded SVG cleaned?
It can be. The settings let you remove scripts, metadata, comments, and embedded raster images, plus normalize viewBox and sizing.
Can I make the SVG single color?
Yes. Use the single-color SVG file preset or choose force single fill color in the settings.
Can I copy the decoded SVG code?
Yes. Use Copy SVG or Copy decoded text after the Base64 input has been decoded successfully.
What are the usage limits?
Client-side SVG decoding and cleanup are not rate limited because they run in your browser. Backend raster tracing is rate limited to 120 conversions per minute, 400 every 5 minutes, 1500 per hour, and 3000 per day per IP and browser profile.
