Real feedback from graphic designers, freelancers, and students who use StackFlow Tools daily.
I remove backgrounds for product photos on Daraz every day. Used to pay for Remove.bg but their free version gives low resolution. StackFlow gives full resolution free and my photos never leave my phone. Exactly what I needed.
My client sends 8MB photos that won't upload to the form. I paste them into the compressor and get 400KB in seconds. The Target KB mode is genius — I type exactly what size I need and it hits it perfectly.
Client sent a very small logo and needed it for a banner. Other free tools made it blurry. StackFlow upscaler kept it sharp even at 4x size. Saved me from going back to the client for a better file.
I build WordPress websites and need WebP format for page speed. This tool converts my entire batch of JPEGs at once. No signup, no limit — I use it on every single project now.
University required photos under 200KB for the application form. Every tool I tried added a watermark or asked for payment. StackFlow just worked — free, clean, no account needed. Submitted in 2 minutes.
I send this site to every client who asks me where to compress or convert images. It is my go-to recommendation. Fast, private, works on mobile — everything works exactly as described. No surprises.
