Frequently asked questions
Are free online image tools safe to use?
They are safe when your file never leaves your device. PicsSizer tools run in your browser, so your images are not uploaded to a server.
Do PicsSizer tools upload my images?
No. Your files are processed in your browser and stay on your device. Some tools download an engine the first time you use them, but your files are never sent anywhere.
Can I edit images online without signing up?
Yes. Every tool works without an account, an email address or a sign-up. Open a tool, add your file and download the result.
Is there a watermark on the output?
No. Files you download have no watermark. The only exception is a watermark you add yourself with the Image Watermark tool.
How do I resize an image online for free?
Open the Image Resizer, add your photo and set a new width and height. Then download the resized file.
How do I make an image file smaller?
Use the Image Compressor. Lower the quality or pick a target size such as 200 KB, then download. Fewer pixels also make a smaller file.
How do I convert an image to another format?
Open the Image Converter, add your file and pick the new format, such as JPG, PNG or WebP.
How do I convert images to PDF, or a PDF to images?
Use Image to PDF to put one or more photos into a single PDF. Use PDF to Image to save the pages of a PDF as pictures.
What size should images be for a website?
It depends on where the image goes. A full-width banner needs far more pixels than a thumbnail. The image size guide lists common sizes for websites and social media.
Can I use PicsSizer on my phone?
Yes. Every tool works in the browser on iPhone and Android, with no app to install. Very large files can be slower on a phone, because the work happens on your device.
