Free online toolsthat never upload your files

How the tools work
Step 01
Pick a tool
Choose the task you need from the list above, for example merge PDF, remove a background or calculate severance pay.
Step 02
Add your file or your numbers
Drop a file on the tool or type the values. Files and numbers are not sent over the network, the work happens on your own device. The event gift list is the one exception: it saves the list you create so your guests can open it.
Step 03
Adjust the options
Set the quality, the page ranges, the background color or the calculation details. The result updates as you go.
Step 04
Download or copy the result
Save the new file, copy the link or read the calculation. There is no watermark and no account to create.
What you get
Private by design
The tools are programs that run in your browser. No server receives your documents, photos, videos or salary, so there is nothing to leak. The only tool that stores anything is the event gift list, and it stores only the list you choose to create.
Free without strings
No sign up, no daily limit and no watermark on the result. The site may show ads on the tool pages to help cover the cost of keeping it online.
Fast and always at hand
Nothing to upload or wait for. The tools work on phones and computers, and the site can be installed as an app to open them in one tap.
Built and maintained by one engineer
Made by Hiran Travassos, a senior software engineer. The payroll tables carry their reference year and the date they were last checked against the official publications.
Which tool do you need?
To work with PDF files, use PDF Helper: Merge PDF joins several documents into one, Split PDF extracts pages or cuts a long file into parts, Compress PDF makes a heavy file small enough to send by email or to pass an upload limit, and Edit PDF adds text, images and a signature to a document.
To edit images, the Background remover cuts out the subject of a photo with an AI model that runs in your browser, and gives you a transparent PNG or a solid color behind it. To work with video, Video to MP3 pulls the audio out of an MP4, MOV, WebM or MKV file.
To talk to customers, the WhatsApp link generator turns a phone number and a message into a wa.me link, an HTML snippet and a QR code you can print or share. To plan a wedding, a baby shower or a party, the event gift list gives you a link of your own where guests see the gifts, with pictures and prices, and reserve the one they will give.
For Brazilian employment and money questions, the accounting calculators cover net salary (CLT), severance pay, vacation pay, the 13th salary, overtime, SAC and Price financing and compound interest, always with the explanation of how each number was reached.
