Testimonials
Loved by creators who need face blurring fast
Don't just take our word for it. Here's what creators say after using Blur Fish.
“Automatic face detection gets me most of the way there, then I swap in the blur shape or emoji I want. It’s the fastest way I’ve found to prep creator content.”
Anita Cvetnic
Canva creator
“I upload a photo, Blur Fish finds the faces, and I can switch each one to a square, circle, or emoji in seconds. Exporting at the original file size is a huge plus.”
Joao
Small business owner
“For event photos, the auto-detected faces save me time. I can keep everything on-brand by replacing faces with clean blur shapes instead of messy edits.”
Joelle Perrody
Social media manager
“I use the face mask option when I want a softer look and emojis when I want something more playful. Automatic detection means I’m not lining faces up by hand.”
Jorge Perez
Teacher
“The square, circle, and rectangle blur options make mockups look polished fast. I also like that the export keeps the original file size for client handoff.”
Kevin Leech
Product designer
“I only need face privacy, and this does exactly that. Auto detection plus quick shape swaps lets me finish selects without opening a heavier editor.”
Khaled Orfali
Photographer
“For community photos, I can detect faces automatically and replace them with emojis in a couple of clicks. It’s simple enough to use even when I’m moving fast.”
Lisa Cozzetti
Community manager
“I like that I can choose between a clean blur shape and an emoji depending on the post. Keeping the original file size on export makes publishing easier.”
Lucas Froese
Content creator
“Listing photos sometimes catch people in the background, and Blur Fish fixes that fast. It finds the faces and lets me drop in a blur shape without reducing export quality.”
