Why use MergeCompress?
Private by design
Most online tools upload your files to a server. Ours never do — everything happens locally in your browser tab, so sensitive documents stay yours.
Free, no strings attached
No accounts, no subscriptions, no watermarks stamped on your files, no daily limits nagging you to upgrade.
Fast and simple
No installs, no waiting in upload queues. Pick a tool, drop your files, adjust one or two settings, download the result.
Works everywhere
Any modern browser on Windows, Mac, Linux, Android or iOS. Nothing to install, nothing to update.
Frequently asked questions
Are these tools really free?
Yes. Every tool on MergeCompress is free to use with no account, no watermarks and no usage caps hidden behind a paywall.
Do you upload my files to a server?
No. All processing happens locally in your browser using JavaScript. Your files never leave your device, which also means the tools work offline once the page has loaded.
Will there be a watermark on my files?
Never. Output files are clean — no branding, no watermarks, no footer text added.
Which browsers are supported?
Any up-to-date version of Chrome, Edge, Firefox or Safari, on desktop or mobile. Very old browsers may lack the features these tools rely on.
Is there a file size limit?
There is no server-side limit because there is no server. The practical limit is your device's memory — extremely large PDFs (hundreds of megabytes) may be slow on older phones.
