Frequently Asked Questions (FAQ)

Answers from the site admin to the questions we get most often.

QIs this tool really free? Is there a paid plan?
Adminreplied

Yes. Every photo and PDF tool here is free, with no account, no sign-up and no watermark added by us. The site is supported by advertising and optional donations.

QWhy do I have to watch an ad before downloading?
Adminreplied

Hosting and maintaining these tools costs money, and a short video ad before your download is how the site stays free. If an ad blocker is on, the site asks you to turn it off for this page.

QAre my photos and PDF files uploaded to a server?
Adminreplied

No. Your files are processed inside your own browser and are not sent to our servers. One exception: the Smart cutout in the background changer downloads a small AI model from a public network the first time you use it, so it needs an internet connection once. The model comes to your device; your photo does not leave it.

QWhich passport photo sizes are supported?
Adminreplied

35×45 mm (commonly used for India, UK and EU applications), 51×51 mm / 2×2 inch (USA), 33×48 mm (China), 40×60 mm and 30×40 mm, all at 300 DPI, with print sheets for 4×6 inch, 5×7 inch or A4 paper. Rules differ by country and application, so check your issuing authority’s requirements before submitting.

QHow does the photo background changer work?
Adminreplied

It can cut out the person with Smart cutout, or remove a plain wall by colour. Results are best when the photo is sharp and evenly lit with the face and shoulders clearly visible. Check the edges around hair and beard, and try the other method if something looks off.

QCan I compress an image to 50 KB or 100 KB?
Adminreplied

Yes. In Image Compressor enter a target size in KB. The tool tries quality levels, and reduces the dimensions if needed, until the file fits. This is handy for exam, job and government form uploads.

QHow do I convert JPG to PDF?
Adminreplied

Open JPG to PDF (Images to PDF), add your JPG or PNG pictures, arrange them, press the button and download one PDF.

QHow do I merge PDF files into one?
Adminreplied

Open Merge PDF, add your files in the order you want, press Merge PDF and download the combined document.

QCan I add a watermark to a PDF or an image, or remove one?
Adminreplied

You can add a text watermark to a PDF with Add Watermark to PDF and to pictures with Add Watermark to Image. This site does not remove existing watermarks.

QCan I unlock a password-protected PDF?
Adminreplied

Unlock PDF removes restrictions such as copy or print limits. If a file needs a password to open, enter the password you already have. It cannot recover a forgotten password.

QIs there a file size limit, and which browsers work?
Adminreplied

We do not set a fixed limit; the practical limit is your device memory, so work in smaller parts for very large PDFs or photos. Current Chrome, Edge, Firefox and Safari on Android, iPhone, iPad, Windows, macOS and Linux are supported. HEIC photos are not read by most browsers, so convert them to JPG first.

QWill compressing or converting reduce quality?
Adminreplied

Image tools let you choose the quality, and PNG output is lossless. Compress PDF re-encodes pages to reduce size, so pick a higher quality setting if text must stay sharp. Protect PDF and PDF to PowerPoint turn pages into images, so text in the result is not selectable. Always keep your originals.
