Guides
All guides →- Etsy SEO: how to get found in Etsy search
How Etsy decides which listings to show, and what you can change: titles, tags, attributes, photos, shipping and service.
- JPG vs PNG vs WebP: which format should you use?
Photos, screenshots, logos and websites each suit a different format. Here is how to pick, and what you lose when you convert.
- How to reduce an image to under 1 MB
Upload forms and email often cap images at 1 MB. Resize, compress, then choose the right format, in that order.
- How to convert HEIC photos to JPG
iPhones save photos as HEIC, which many apps and Windows PCs can’t open. Here are the quickest ways to get JPGs.
- What DPI do you need for printing?
300 DPI is the usual answer, but what really decides print quality is how many pixels you have for the size you want.
- How to remove EXIF data and location from photos
Photos can reveal where and when they were taken, and on what. Here is how to check, and how to remove it before you share.
Why nothing gets uploaded
Most online converters send your file to a server, process it there and send it back. That's slower, and it means a copy of your photo sits on someone else's computer.
Flynn's Tools does the work inside your browser instead. Screenshots with private details, family photos and client work never leave your device. You can verify it: open your browser's Network tab while you use any tool.
Questions
Is it really free?
Yes. Every tool here is free to use, with no sign-up and no watermark.
How can the tools work without uploading?
Modern browsers can decode, edit and encode images on their own. The page loads the tool once, then all the work happens on your device.
Is there a file size limit?
Files up to 80 MB are accepted. Images up to 64 megapixels work on computers, 36 on Android phones and 16 on iPhone and iPad. Those limits come from how much memory browsers can safely use.
Which formats are supported?
The tools read JPG, PNG, WebP, GIF, AVIF, BMP, HEIC, TIFF and SVG. They save as JPG, PNG or WebP, and some tools also make GIF, PDF, ICO or ZIP files.
