Quick answer
Basic Social images handling is usually free; a local browser tool can convert/compress/check it. Social platforms recompress; crop to recommended dimensions and avoid tiny text.
Why it matters
Rule out free options before paying for software or a service.
Covers, squares and vertical images use different dimensions.
Step by step
- Back up the original; never overwrite the only copy.
- Confirm the target platform's format, dimensions and size limit.
- Cap the longest side first, then quality; change one variable at a time.
- Compare size and sharpness after compressing, and step back one setting if needed.
- Keep the original until the output is confirmed.
Common mistakes
- Chasing the smallest file and blurring text/edges.
- Converting transparent PNG to JPEG, turning transparency white or black.
- Recompressing the same file and accumulating loss.
- Overwriting the original, so a bad result cannot be undone.
Checklist
- Original backed up.
- Output format/dimensions/size meet the platform.
- Text is readable and transparency is correct.
- Verified in the real page/email/upload field.
- Original kept until confirmed.
Key facts
- Covers, squares and vertical images use different dimensions.
- Large type and little text survive compression better.
