Popular uses
HEIC to JPG
iPhone photos are saved as HEIC, which many Windows programs, websites and email systems cannot open. Convert them to JPG in one step.
Resize images in bulk
Shrink a whole folder of photos for a website, an email or a WhatsApp message. Scale by percentage, set an exact size or choose a preset.
Merge and split PDFs
Combine several PDFs into one, reorder pages, rotate scanned pages the right way up, delete pages you do not need, or split a PDF into single pages.
Image to PDF
Turn a photo, scan or screenshot into a PDF you can email or upload to a form.
Frequently asked questions
Is this file converter free?
Yes. It is free with no sign-up, no watermark and no file limit other than what your device can handle.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device, so your photos and documents stay private. The tool does need an internet connection the first time to load the conversion libraries.
How do I convert HEIC to JPG?
Open the Convert tab, drop in your HEIC or HEIF photos from your iPhone, choose JPG as the target and click Convert. You can convert many photos at once and download them all as a zip.
Can I convert RAW photos such as DNG, CR2 or NEF?
Partly. Browsers cannot process raw sensor data, so for RAW files the tool uses the full-size JPEG preview that is stored inside the file. It is fine for sharing, but it is not a full raw develop.
How do I merge PDF files?
Open the PDF Toolkit tab, add your PDFs, put them in the order you want with the arrow buttons, and click Merge & Download.
Can I split a PDF or remove pages?
Yes. Upload a PDF in the page editor, drag the thumbnails to reorder, rotate or remove pages, then download the edited PDF or split every page into its own file in a zip.
Does PDF to Word keep the formatting?
No. PDF to DOCX and DOCX to PDF are text-based conversions, so the text comes across but layout, images and tables do not. For layout-heavy documents use a desktop tool.
How do I make a photo smaller?
Use the Resize tab to scale images by a percentage, set an exact width and height, or pick a preset size. You can also convert to JPG or WEBP and lower the quality slider in the Convert tab.
