Frequently asked questions

How to convert, compress and edit your files, which formats and devices are supported, and what to do when something goes wrong.

Files never leave your device.

Converting files

How do I convert HEIC to JPG for free?

Open the HEIC to JPG converter, add your iPhone photos, choose a quality and press Convert. You can convert a whole batch and download the JPGs together as a ZIP. To stop your iPhone saving HEIC in future, go to Settings, Camera, Formats and choose Most Compatible.

How do I change a WebP image to JPG or PNG?

Use WebP to JPG for photos, or WebP to PNG to keep transparent backgrounds. Add the images you saved from a website, convert, and download. AVIF images work the same way with AVIF to JPG.

How can I reduce the size of a PDF file?

Add the PDF to the PDF compressor and pick a compression level. Scanned and image-heavy PDFs shrink the most, often by 50 to 90 percent, which makes them small enough to email or upload to forms with size limits.

How do I combine PDF files into one?

Open Merge PDF, add your files, put them in the order you want with the arrows, and press Merge. Pages are copied without any loss of quality, and there’s no limit on the number of files.

How do I convert JPG images to a PDF?

Use JPG to PDF to put one or many photos into a single PDF, with A4, Letter or fit-to-image pages. There are also PNG to PDF and HEIC to PDF for screenshots and iPhone photos.

How do I make an image smaller in KB?

Use the image compressor to lower the quality or set a target size in KB, or resize the image to fewer pixels. Combining both is the quickest way to meet an upload limit like 100 KB or 2 MB.

How do I convert M4A or WAV to MP3?

Open M4A to MP3 for iPhone voice memos or WAV to MP3 for recordings, choose a bitrate such as 192 kbps, and convert. MP3 plays on every phone, car stereo and app.

How do I open a ZIP file online?

Add the archive to Unzip Files to see every file inside and download them one by one or all at once. To create an archive, use Zip Files, which also accepts whole folders.

How do I sign a PDF without printing it?

Open Sign PDF, add the document, then draw, type or upload your signature and drag it into place on the page. Choose the last page, every page or a specific page, and download the signed PDF.

Is TheFilesGuy free to use?

Yes. Every tool is completely free, with no sign-up, no daily limit and no watermark on your files. There’s no trial and no paid version.

Can I use these tools on my phone or iPad?

Yes. All tools work on iPhone, iPad and Android as well as on Windows and Mac computers, in Safari, Chrome, Edge and Firefox. Very large files may be slower on phones.

Is there a file size limit?

There’s no fixed limit. Large files depend on your device’s memory, and files over 100 MB show a warning because they can be slow on phones.

Do I need to install any software?

No. Everything works on the website, so there’s nothing to download or install. You can bookmark the tools you use most.

Which file formats are supported?

Images such as HEIC, WebP, AVIF, PNG, JPG, GIF, TIFF and BMP; PDF; audio such as MP3, WAV, M4A, AAC, FLAC and OGG; ZIP and other archives; and data files like CSV, JSON, XML, YAML and Excel. The file format library explains 145 file types.

Privacy and safety

Are my files uploaded anywhere?

No. Every tool runs inside your browser on your own device. Files are read, processed and saved locally, and the site’s security policy blocks the page from sending data to any other website.

Do you keep copies of my files?

No. We never receive your files, so there is nothing to keep. Results live in your browser’s memory until you download them or close the tab.

Do I need an account?

No. There are no accounts, no sign-up and no email required.

Does the site use cookies or tracking?

No. The site sets no cookies and loads no analytics or advertising trackers. See the privacy policy for details.

Using the tools

Is there a file size limit?

There is no fixed cap. The practical limit is your device’s memory. Files over 100 MB show a warning, because they may be slow or fail on phones.

Can I convert many files at once?

Yes. Most tools accept a batch, show progress for each file and let you download everything as one ZIP.

Does it work offline?

Yes. After your first visit, pages load without a connection, and each tool works offline once you have used it once.

Which browsers are supported?

Current versions of Chrome, Edge, Firefox and Safari on desktop and mobile. Very old browsers may be missing features some tools need.

Do the results have a watermark?

No. You get just your file. The only watermark is one you add yourself with the Add Watermark to PDF tool.

Limits

Why is there no PDF to Word or video converter?

Those conversions need either a server or very large in-browser engines. We only offer tools that run fully in your browser.

Why did a file fail to convert?

Usually the file is damaged, password-protected, or uses a variant of the format your browser can’t read. The error message under the file explains what went wrong and what to try.

Can you remove a password I don’t know?

No. The Unlock PDF tool removes a password only when you type it. It cannot guess or bypass passwords.

Cost and support

Is it really free?

Yes. All tools are free to use, with no trial or paid tier.

How do I report a problem or suggest a tool?

Email hello@thefilesguy.com. Include the tool you used, your browser and the error message. Please don’t attach private files.
