Can I change the image order before creating the PDF?
Yes. Arrange the JPG and PNG files before conversion so the final PDF reads in the right order. This matters for receipts, ID scans, forms, classroom work, or photo packets where the browser can build the document locally but cannot guess the sequence you intended.
Can it handle lots of images at once?
It can handle batches, but the practical limit depends on your device memory, browser, and image size. Large phone photos can consume a lot of RAM when converted. If the browser slows down, reduce image count, resize the images first, or split the job into smaller PDFs.
Do my images get sent anywhere?
No. The images are read by the browser and written into a PDF on your device. That is useful for IDs, receipts, medical scans, and other photos you do not want to upload just to combine into a document. The output downloads locally when conversion finishes.
Will image quality change?
PDFTasker aims to keep the source images clear, but quality still depends on the original files and browser handling. If a source photo is blurry, dark, or cropped badly, converting it to PDF will not fix that. Review the result before sending it to a portal or recipient.
When should I use a scanner app instead?
Use a scanner app first when you need perspective correction, automatic edge detection, OCR, or cleanup before the PDF is built. PDFTasker is best after you already have usable JPG or PNG files and want to package them without sending the images to a server.
