Quick answer
Resize the image to the destination's needed pixel dimensions first. Then export a JPG photograph at a moderate quality or a PNG graphic with only the colors and transparency it needs. Compare the result at phone size. Stop compressing when text edges, faces, gradients, or product details begin to break.
Source check: August 28, 2026. Platform apps, APIs, account types, and third-party publishers can change on different schedules. The final operational check is the preview and public result in the exact path you use.

What this page owns
Compression is not the first fix for an oversized source. A 6000-pixel photo does not need to stay 6000 pixels for a 1080-pixel post. Resize once from the original, then compress the correctly sized export.
That ownership boundary matters. Boomp uses one clear page for each search job instead of publishing near-duplicate pages that give different answers to the same question.
A dependable production method
- Keep the original source untouched.
- Resize to the required canvas.
- Choose JPG or PNG by content type.
- Compare before and after at actual display size.
- Upload and inspect the processed platform version.
The last check matters most. A design file, successful export, scheduler acceptance, or API response does not prove that the customer-facing artifact is correct.
Size is only one acceptance test
A technically valid file can still fail the business. Check these questions with the final media and caption together:
- Is every name, date, price, claim, location, and link current?
- Does the crop preserve the subject and the useful words?
- Are captions, contrast, and text alternatives sufficient for the content?
- Does the business have permission to use the people, customer material, music, footage, and marks shown?
- Does the call to action match the destination and what happens next?
- Did a responsible person approve this exact version?
For the full release gate, use the social media content quality checklist.
Where Boomp fits
Boomp fits when the recurring problem is larger than one pixel count. The current first look starts with a public website and returns up to six website-grounded talking points before email. Those talking points are not finished posts and do not prove that Boomp knows the owner's voice. Email saves the first look and continues into post ideas. Finished media and posts belong to paid work, with the customer's approval settings controlling what represents the business.
Give Boomp your public website and review the first talking points before email.
