What size should I export for Instagram?

Instagram displays images at 1080 px wide. For square posts use 1080 x 1080, for portrait 1080 x 1350 (4:5 ratio, recommended for art), for landscape 1080 x 608. Stories are 1080 x 1920.

Should I export as JPEG or PNG?

JPEG is best for photographs and paintings (smaller files, good colour). PNG is best for graphics with sharp edges, text, or transparency. For social media, JPEG at high quality is usually the best balance.

Will social media platforms compress my images?

Yes — Instagram, Twitter and Facebook all recompress uploads. Upload at the recommended resolution and high quality to minimise the damage. Some artists add 2-3% sharpening before upload to compensate.

What resolution for web portfolios?

The longest edge should be 1500-2000 px for web portfolios. This is large enough for full-screen viewing but prevents easy high-quality reproduction. Add a watermark if piracy is a concern.

How do I export for giclée printing?

Export at 300 DPI in TIFF or high-quality JPEG. For A4, this means 2480 x 3508 px minimum. Use your working colour profile (sRGB or Adobe RGB) and embed the profile in the file.

How Export Size Calculation Works

Export size = Source scaled to fit within target maximum dimensions

The calculator scales your source image to fit within the target platform maximum dimensions while maintaining the original aspect ratio. It never upscales — if your source is smaller, the export matches the source. File size is estimated based on format and quality setting.
