For Windows 10 and 11
Sunflower converts and edits files the moment you drag them. Start dragging any picture, PDF or Word file, press Shift, and drop it on a slice. The result lands right next to the original.
Works offline · No account · Your originals are never changed
Sunflower lives quietly in the tray. It wakes up only when you need it, right where your file already is.
Any picture, PDF, Word or text file, in File Explorer or on the desktop.
A glass menu opens under your cursor. Tap Shift again to switch between Convert, Tools and Studio.
The new file appears next to the original, with Open, Show in folder and Undo in the notification.
Sunflower only shows what fits the file you're holding.
JPG, PNG, WebP, HEIC, AVIF, TIFF, BMP, GIF, ICO and PDF. PDF to pictures, Word or text. Word and text to PDF. Several pictures into one PDF.
Compress, resize, crop and edit pictures. Annotate, redact, add a background, remove GPS location. PDFs: compress, split, merge, rotate, password-protect, extract images.
Scan fix, Cut out, watermarks, rounded corners, icon sets, page numbers, PDF signing and document packets.
Scan fix
Sunflower finds the page, straightens it, removes shadows and makes the paper white. Choose colour, grey or black-and-white, and drag the corners if you want them exact. Several photos become one PDF.


Cut out
Built-in AI finds the subject in people, pets and product photos. Keep it transparent, or put it on white, your own colour or a soft blur. It runs on your PC, so nothing is uploaded.
Sign
Draw your signature once with the mouse or a pen, or use a photo of it. Click where it goes, add today's date if you like, and Sunflower remembers it for next time.


Document packet
Drop pictures, PDFs, Word and text files together and drag them into order. You get one PDF with a clickable contents page, bookmarks, page numbers and every page in A4. Ideal for applications, claims and reports.
Watermark
Text or your logo, across the middle, tiled or in a corner, on pictures and on every page of a PDF. Set the colour, size and opacity with a live preview.

Six colour themes for the menu, windows and notifications. Pick Shift, Ctrl or Alt as your key, and choose where results are saved.

Converting, scanning, removing backgrounds and signing all run on your computer. No uploads, no cloud.
Every result is a new file next to the original. Changed your mind? Undo sends it to the Recycle Bin.
Sunflower collects nothing about you or your files. Read the privacy policy.
Every feature in one app, with updates through Microsoft Store.

Launching on Microsoft Store

Both work. Right-click a file and choose Open with → Sunflower, or double-click the tray icon to pick a file. The same menu opens.
Only while you're holding a file. If Shift clashes with how you work, switch the key to Ctrl or Alt in Settings, or turn Sunflower off from the tray.
