An Online Universal Image Converter is a versatile web-based utility designed to transform images between various popular formats and to convert images to/from Base64 text representations. Supported conversions include popular raster formats like JPG (JPEG), PNG, WebP, BMP, and also encoding images to Base64 Data URLs (stored in .txt files) or decoding Base64 Data URLs (from .txt files) back into image formats.
This all-in-one converter operates entirely within your web browser (client-side). This means your image files and Base64 data are never uploaded to any servers, ensuring complete privacy, enabling swift conversions, and giving you full control over your data.
- Add Your Files: Drag and drop your files onto the designated area (
#dropArea), or click the area to browse and select files. You can upload:- Image files:
.jpg,.png,.webp,.bmp. - Text files (
.txt) containing Base64 Data URLs (e.g.,data:image/png;base64,...) if you intend to convert Base64 to an image.
#previewContainer). - Image files:
- Select Target Format: Once files are added, choose your desired output format from the "Convert to:" dropdown menu (
#conversionFormatSelect). Options include:- Image formats: PNG, JPG, WebP.
- "Base64 (Text File)" to encode an image into a Base64 Data URL within a
.txtfile. - "PNG (from Base64)", "JPG (from Base64)", "WebP (from Base64)" to decode a Base64 string (from an uploaded
.txtfile) into the specified image format.
- Convert Files: Click the "Convert to [Selected Format] " button (
#convertBtn). The tool will process each applicable file. A loading indicator (#loadingBaror#loadingOverlay) shows progress. - Download Converted Files: Converted files will be automatically downloaded to your device. They will be named based on the original filename and the new extension (e.g.,
original.jpgconverted to PNG becomesoriginal.png). - Clear or Convert More: Use the " Clear All" button (
#clearBtn) to remove all uploaded files. To convert more, simply add new files and select your desired format.
.txt file, ensure the text file contains a valid "Data URL" (e.g., data:image/png;base64,iVBORw...). When converting to Base64, the output will be a .txt file containing this Data URL.
- Secure & Private: All conversions happen locally in your browser. No files are uploaded to servers.
- Client-Side Processing: Fast and efficient conversions using your device's resources.
- Multi-Format Support:
- Convert between JPG, PNG, WebP, BMP.
- Encode images (JPG, PNG, WebP, BMP) to Base64 Data URLs (output as
.txt). - Decode Base64 Data URLs (from
.txt) to PNG, JPG, or WebP images.
- Batch Conversion: Process multiple files simultaneously.
- User-Friendly Interface: Simple drag-and-drop and clear options.
- File Previews: See thumbnails of uploaded images or icons for text files.
- Automatic Downloads: Converted files are downloaded directly.
- Transparency Handling:
- Preserves transparency when converting between formats that support it (e.g., PNG to WebP).
- Adds a white background if converting a transparent image to a format that doesn't support transparency (e.g., PNG to JPG).
- Completely Free: Unlimited conversions without cost or registration.
- No Software Installation: Works in all modern web browsers.
Image to Image (e.g., JPG to PNG, PNG to WebP)
- JPG to PNG: To gain transparency support or ensure lossless quality for graphics.
- PNG to JPG: To reduce file size for photographs, at the cost of losing transparency and some quality (lossy compression).
- To WebP: To achieve smaller file sizes with good quality (lossy or lossless) and transparency support, ideal for web use.
- From WebP/BMP: To convert to more universally compatible formats like PNG or JPG if needed for older software or specific platforms.
Image to Base64 (Text File)
- Purpose: To embed small images directly into HTML, CSS, or other text-based documents, reducing HTTP requests. The output
.txtfile contains the Data URL. - Use Case: Embedding icons, small logos directly into web pages or email templates.
Base64 (Text File) to Image
- Purpose: To extract an image that is embedded as a Base64 Data URL within a text file (e.g., from source code, JSON).
- Use Case: Retrieving an image from an HTML/CSS snippet or a configuration file to use it as a standalone image file.
Note on BMP: While BMP files can be uploaded and converted *from*, this tool primarily focuses on outputting to more web-friendly formats (PNG, JPG, WebP) or Base64. Direct conversion *to* BMP is not a primary feature here.
- Versatility: Handle a wide range of common image conversion needs in one place.
- File Size Optimization: Convert to formats like WebP or JPG to reduce image sizes for faster web loading.
- Manage Transparency: Convert to PNG or WebP to maintain or add transparency, or to JPG to remove it.
- Web Development Aid: Easily generate or decode Base64 Data URLs for embedding images.
- Efficiency: Batch process multiple files to save time.
- Privacy Assured: Client-side operations mean your files stay on your computer.
Your Files and Data Remain Yours
Client-Side Operations
All file processing, including image format conversion and Base64 encoding/decoding, happens directly within your web browser. Your files are never uploaded to our servers.
No File Storage or Logging
We do not store, log, or monitor any of the files you convert or the resulting output. Your data remains confidential to you.
Absolutely Free & Unlimited
Utilize this Universal Image Converter as much as you need without any cost, registration, or limitations.
By using this tool, you agree to our Terms of Service and Privacy Policy. We are committed to protecting your privacy and providing a secure, serverless experience for all your conversion needs.
What file types can I upload?
You can upload common image files (.jpg, .png, .webp, .bmp) and text files (.txt) that contain Base64 Data URLs if you are converting from Base64 to an image.
Will image quality be lost during conversion?
It depends on the conversion:
- Converting to a lossless format like PNG (from another lossless format or a high-quality source) will preserve quality.
- Converting to a lossy format like JPG will result in some quality loss to achieve smaller file sizes. The tool uses a high-quality setting for JPG (around 90-92%).
- WebP can be lossless or lossy; this tool uses a high-quality lossy setting for WebP output to balance size and quality.
- Base64 encoding/decoding itself is lossless, but the underlying image format dictates the quality.
Is this universal converter secure to use?
Yes, absolutely. All processing is done client-side in your browser. No files are uploaded to any server, ensuring your data privacy.
How do I convert a Base64 string from a .txt file to an image?
Upload the .txt file containing the Base64 Data URL. Then, from the "Convert to:" dropdown, select your desired image output format, such as "PNG (from Base64)", "JPG (from Base64)", or "WebP (from Base64)". Click convert, and the image will be downloaded.
Can I convert an image to BMP format?
This tool allows you to upload BMP files and convert *from* BMP to other formats (like PNG, JPG, WebP). However, direct conversion *to* the BMP format is not offered as an output option, as the focus is on more common and web-optimized formats.
What happens with animated GIFs?
This tool primarily processes static images. If an animated GIF is uploaded, typically only the first frame will be processed and converted when targeting formats like PNG, JPG, WebP, or Base64. The animation will be lost.
