Online Image Tools for Everyday Tasks
If you have ever needed to convert a JPEG to PNG, shrink a photo before emailing it, or pull EXIF data out of an image file, you know how annoying it can be to hunt down the right software for the job. These image tools handle all of that directly in your browser - no downloads, no signups, no waiting around.
Convert Between Image Formats
The image converter lets you switch between JPEG, PNG, and WebP formats in seconds. Need a PNG for a transparent background? Want to convert to WebP for smaller file sizes on your website? Just drop the image in and pick your output format. You also get control over quality and compression, so you can find the right balance between file size and image clarity. It is one of the most common image tasks out there, and this tool makes it painless.
Base64 Image Encoding and Decoding
Developers regularly need to embed images directly into HTML, CSS, or JSON without linking to separate files. The Base64 encoder converts any image into a Base64 string you can paste right into your code. It works the other way too - if you have a Base64 string and want to see the actual image or save it as a file, the decoder handles that. This is especially useful for email templates, inline icons, and anywhere you want to avoid extra HTTP requests.
Finding Aspect Ratios and Image Dimensions
When you are working with images for a website or social media, knowing the exact aspect ratio matters. The aspect ratio finder takes your image and tells you its dimensions, ratio, file size, and other technical details. This is handy when you need to crop images to specific proportions, check whether a photo meets upload requirements for a platform, or just figure out what size something actually is before resizing it.
Extracting Image Metadata to JSON
Every image file carries hidden data - things like camera model, GPS coordinates, date taken, exposure settings, and color profile. The metadata extractor reads all of that and gives it to you in clean JSON format. Photographers use it to check shooting details, developers use it to process image data programmatically, and anyone concerned about privacy can see exactly what information their photos contain before sharing them online.
Turning Multiple Images into a PDF
Sometimes you just need to combine a bunch of images into one document. The images to PDF tool lets you upload multiple JPEG, PNG, WebP, or GIF files and merge them into a single PDF. It is great for putting together photo collections, creating simple portfolios, compiling scanned documents, or packaging screenshots into one shareable file. You can reorder the images before generating the PDF so everything ends up in the right sequence.
Everything Runs in Your Browser
This collection of image tools is designed to keep your files on your device. Whether you are checking dimensions, pulling metadata, encoding for the web, or merging photos into a document, the processing happens locally in your browser. That means no upload queues, no server-side storage of your images, and no risk of your files sitting on someone else's infrastructure. You get the same results you would from desktop software, but without installing anything or creating an account.
Your Data, Your Privacy
Privacy is not a bullet point we added to look good, it is how StackConvert is actually built. For most of the tools here, conversion and processing happen entirely in your browser. Your files never reach a server, never sit on someone else's hard drive, and never pass through a third-party pipeline. What goes in stays on your device.
For the handful of formats that browsers cannot decode natively, such as HEIC, AVIF, TIFF, or advanced PDF operations, files are processed over an encrypted connection and deleted the moment conversion finishes. Nothing is cached, logged, or retained. There is no account system tracking your activity, no analytics pixel watching your uploads, and no shadow database of processed files. If that sounds unusual, it is only because so many other tools have trained people to expect the opposite.
StackConvert. Fast tools, honest handling, your files stay yours.
