About DocSizer
DocSizer is a small set of free tools for the jobs online forms keep asking for: making a photo fit a size limit, and turning photos and scans into one PDF.
Why it exists
Filling in an online form can stop on something simple. The photo is a few megabytes too big, the signature has to be a set number of pixels wide, or the documents must be one PDF. Most tools that fix this ask you to upload your personal files to a server.
DocSizer was built so you do not have to. The tools run inside your own browser, so your photos and documents stay on your device.
What you can do here
- Resize a photo or signature to a size in KB and pixels
- Merge JPG, PNG, WebP and PDF files into one PDF
- Resize an image to 50 KB in a few taps
More tools will be added over time.
How we work
- Free to use. No sign-up and no watermark on your files.
- Private by design. Your files are processed on your device and are not uploaded.
- Honest about limits. Every form has its own rules, so we ask you to check yours and we never claim a tool fits every form.
Who is behind it
DocSizer is built and maintained by Hariom, a web developer from India who also runs Brandinza, a web design and digital marketing agency.
