- Blog featured image and social sharing: 1200 × 630 px.
- Instagram post: 1080 × 1080 px (square) or 1080 × 1350 px (portrait).
- Google Business Profile photos: at least 720 × 720 px; 1080 px or more looks best.
- Product photos: square, 1000 to 2000 px, so zoom works.
JPG, PNG or WebP?
JPG suits photos and works everywhere. PNG keeps sharp edges and transparency, so it suits logos, icons and screenshots, but photo PNGs are huge. WebP does both jobs at a smaller size and works in every modern browser, which makes it the best choice for websites. For email attachments and forms that ask for JPG, stick with JPG.
Resizing keeps quality, enlarging doesn't
Making an image smaller keeps it sharp. Making it bigger than the original can't add detail; it just stretches the pixels and looks soft. If a website needs larger images than you have, the fix is better source photos. After resizing, use the image compressor to hit an exact file size, or check a whole page's weight with the page size checker.
About the image Resizer & Converter.
Does resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging beyond the original size makes it look soft.
Can I convert HEIC iPhone photos?
Only in browsers that can open HEIC, which today is mainly Safari. On other browsers, set your iPhone to save photos as JPG (Settings, Camera, Formats, Most Compatible).
Will transparent PNGs stay transparent?
Yes if you convert to PNG or WebP. JPG has no transparency, so transparent areas become white.
Are my images uploaded anywhere?
No. Everything happens in your browser.
How many images can I resize at once?
As many as your device can handle; dozens is fine on most computers.
