Launch Tool

Image to Base64

Encode JPG, PNG, GIF, SVG, or WebP images as data URLs for HTML and CSS. Inline images skip a request but cannot be cached on their own.

Launch Tool

PNG to Base64

Encode a PNG as a Base64 data URL with transparency intact. Icons and logos suit this best, since the string grows with the source file.

Launch Tool

JPEG to Base64

Encode a JPEG as a Base64 data URL for inline embedding. Photos make long strings, so this suits thumbnails more than full size images.

Launch Tool

Base64 to XML

Decode Base64 into XML and read it indented, with the declaration and encoding preserved exactly as they were before the string was encoded.

Launch Tool

Base64 to YAML

Decode Base64 into YAML with indentation intact, which matters here more than in most formats, since YAML structure lives in the whitespace.

Launch Tool

CSV to Base64

Encode a CSV file as Base64 for transport inside JSON or an API field. Line endings are preserved exactly, so the round trip stays lossless.

Launch Tool

Base64 to CSV

Decode a Base64 string back into readable CSV, then check the delimiter and row count before you feed the file into a spreadsheet.

Launch Tool

Binary to Base64

Encode raw binary data as Base64 so it travels safely through text-only channels like JSON payloads, email bodies, and query strings.

Launch Tool

Base64 to Binary

Convert Base64 to binary instantly. Free online Base64 to binary decoder with formatting options. No registration required.

Launch Tool

Octal to Base64

Convert octal number sequences into Base64 output, byte by byte. Useful with file permissions or legacy systems that still speak in octal.

Launch Tool

Base64 to Octal

Convert Base64 to octal instantly. Free online Base64 to octal decoder with formatting options. No registration required.

Launch Tool

Base64 to HTML

Decode Base64 into HTML and preview it rendered alongside the source, which is the fastest way to check an encoded email template.

Launch Tool

Base64 to CSS

Convert Base64 to CSS code instantly. Free online Base64 to CSS decoder. No registration required. Decode Base64 strings to CSS.

Launch Tool

Base64 to JavaScript

Decode Base64 back into JavaScript source and read it formatted. Handy when a script arrives encoded inside a config file or a data URL.

Launch Tool

SVG to Base64

Convert SVG files to Base64 encoded strings instantly. Free online tool for embedding SVG graphics in HTML, CSS, or JavaScript.

Launch Tool

BMP to Base64

Encode a BMP as a Base64 data URL with drag and drop and a preview. BMP files are uncompressed, so even a small image makes a very long string.

Launch Tool

GIF to Base64

Encode an animated GIF as a Base64 data URL for HTML or CSS. Every frame is preserved, which is also why the resulting string gets long fast.

Launch Tool

WebP to Base64

Encode WebP images as Base64 data URLs. WebP starts smaller than PNG or JPEG, which keeps the encoded string manageable for inline use.

Launch Tool

AVIF to Base64

Encode AVIF images as Base64 data URLs. AVIF compresses harder than JPEG, so even after the 33 percent Base64 overhead the string stays small.

Launch Tool

APNG to Base64

Encode an animated PNG as a Base64 data URL for HTML or CSS. Animation and alpha both survive, though the string runs about a third larger.

Launch Tool

Base64 Encoder

Encode text to Base64 in the browser, then copy, download, or share the result. The encoded string runs roughly a third longer than the input.

Launch Tool

File to Base64

Convert any file to Base64 online. Free tool supports documents, images, audio, video. Instant conversion, no registration.

Launch Tool

Base64 to File

Free Base64 to file converter. Decode Base64 strings to any file type instantly. Supports images, documents, audio, video & more.

Launch Tool

Audio to Base64

Encode MP3, WAV, or OGG audio into Base64 for inline embedding. Files past a megabyte make unwieldy strings, so keep the clips short.

Launch Tool

Base64 to Audio

Convert Base64 to audio files instantly. Free online Base64 audio decoder with preview and download. No registration required.

Launch Tool

Video to Base64

Encode a video file as Base64 for APIs and data transmission. Even short clips produce enormous strings, so this rarely suits a web page.

Launch Tool

Base64 to Video

Convert Base64 to video files instantly. Free online Base64 video decoder with preview and download. No registration required.

Launch Tool

Hex to Base64

Convert hexadecimal to Base64 encoding instantly. Free online hex to Base64 converter with formatting options. No registration required.

Launch Tool

Base64 to Hex

Convert Base64 to hexadecimal instantly. Free online Base64 to hex decoder with formatting options. No registration required.

Launch Tool

CSS to Base64

Encode a stylesheet as Base64 for a data URL import. Handy for single-file demos, though it costs you separate browser caching of that CSS.

Launch Tool

HTML to Base64

Convert HTML to Base64 encoding instantly. Free online HTML to Base64 converter with real-time conversion, formatting options, and preview.

Launch Tool

Base32 Encode

Encode text to Base32, with padding optional. The alphabet skips easily confused characters, so the output holds up in QR codes and speech.

Launch Tool

Base32 Decode

Decode Base32 back to plain text, with padding handled either way. Base32 avoids lowercase entirely, which is why it survives being read aloud.

Base64 vs Other Encoding Methods

You may choose the best tool for your project by knowing when to utilize Base64 instead of other encoding methods. Here are some common alternatives to Base64 and how they compare.

Base64 vs Hex

Base64 produces more compact output than hexadecimal encoding, reducing data size by approximately 33%.

✓Base64 uses 64 characters vs Hex's 16 characters
✓33% smaller output size with Base64
✓Better for bandwidth-sensitive applications
✓Standard in email attachments and web APIs

Best for: Data transmission

Base64 vs URL Encoding

Base64 handles binary data natively while URL encoding works with text characters for safe URL transmission.

✓Base64 encodes any binary data directly
✓URL encoding preserves readable characters
✓Use Base64URL for URL-safe binary data
✓Combine both for complex data in URLs

Best for: Binary in URLs

Base64 vs Raw Binary

Base64 makes binary data text-safe for protocols that only support ASCII characters.

✓Safe for JSON, XML, and text protocols
✓Works in email without corruption
✓Embeddable directly in HTML/CSS
✓Cross-platform compatibility guaranteed
