StickerGrab
v1.2.0-beta.1
Package screenshots, diagrams, and UI exports into a single PDF without turning them into one-off attachments.
Use Orenvo PDF when loose image files need to become a deliberate document, not another pile of attachments.
Turn PNGs into a PDF
Image to PDF
Combine PNG images into one document.
One document
Turn image sets into a PDF that is easier to send, review, or print.
Order before export
Arrange the pages instead of trusting filename sorting.
Why this workflow
PNGs are great for crisp screenshots, diagrams, and design exports, but awkward when a reviewer expects a document. Orenvo PDF turns those visual assets into one review-ready PDF without forcing every image through a web form.
Format handoff
Image conversion is only one part of the workflow: after you build a PDF from images, the same app also handles merging, compression, and JPG/PNG/WebP format conversion.
How it works
Add the images, arrange the pages, choose the output settings, and export the PDF.
Select the PNG screenshots, diagrams, or exports.
Arrange the sequence so the PDF tells the story clearly.
Set page sizing before export.
Save the PDF locally with no daily export limit or watermark.

Create one review handoff instead of many attachments

The installed app reads images from local folders and writes the PDF to a folder you choose.
Orenvo PDF starts without sign-in, and image-to-PDF exports have no watermarks.
Image-to-PDF exports have no daily limit or watermark.
FAQ
Yes. Add PNGs from one folder or several folders, order them as pages, and export a single PDF.
