Ten tools, sorted by the job

Every tool is free and runs in your browser.

Three steps, all on your device

No upload, no queue, no account. The work happens where your file already is.

  1. Open a tool

    The page and its processing code load in your browser. Then add your file.

  2. Your device does the work

    Images and PDFs are processed locally in memory. Results appear in seconds, even on mobile data.

  3. Download the result

    The new file is saved directly to your device. Nothing is kept online.

Your files never leave your device.

Most online converters upload your documents to a remote server. Every tool here runs locally instead: safer for passports, IDs, signatures and contracts, and quicker too.

Questions people ask

Can't find your answer? Get in touch through the Contact page.

Are my files uploaded when I use UploadWell?

No. Every tool runs inside your web browser using your device's own processing power. Images and PDFs are never sent to our servers or anyone else's.

Is UploadWell really free?

Yes. All tools are free to use with no sign-up, no watermarks and no usage limits. The site is supported by advertising.

Do the tools work on my phone?

Yes. Every tool is designed for touch screens and works in modern mobile browsers such as Chrome, Safari, Samsung Internet and Edge.

How do I reduce a photo to 20 KB or 50 KB for an online form?

Open Compress Image, choose Target size and enter the KB limit, or use the ready-made 20 KB and 50 KB pages. The tool finds the best quality that fits.

Which file types are supported?

Images: JPG, PNG, WebP, HEIC/HEIF (iPhone), GIF, BMP and AVIF where your browser supports it. Documents: PDF.

Why are some tools slower on older phones?

Because processing happens on your device, very large files or many pages need more memory and time on older hardware. Closing other tabs usually helps.

Your form is waiting. So is the tool.

Pick a tool, add your file and download the result. It all happens on your device, and it costs nothing.
