Prepare Images for OnlySocial Posts: Crops, Formats and Quality

Preparing images for OnlySocial posts works best when you begin with the destination and the message, then export the right file. Uploading one large image everywhere can leave a chart unreadable, crop out a product, or attach a landscape composition to a format designed for vertical viewing. A good preparation workflow catches those problems before the post reaches the calendar.

OnlySocial documents separate post versions with different media, and its official updates describe a built-in image editor. Those features can support the workflow, but they do not remove each destination's format requirements. This guide uses practical production examples and a verified Pinterest specification, while distinguishing suggested working canvases from universal platform rules. Always validate the specific account and post format you intend to publish.

Write the visual job before choosing a canvas

Describe what someone should understand from the image in one sentence. For a tutorial, that might be “the calendar contains two versions of the same promotion.” For a service introduction, it could be “this consultant helps small teams organize publishing.” The sentence guides the subject, crop, and amount of detail. If you cannot state the image's job, a larger canvas will not make the communication clearer.

Decide whether the image supports the caption or must communicate independently. A social graphic that will appear without much surrounding context needs a recognizable subject and a clear visual hierarchy. A screenshot demonstrating one control should show that control at readable size. Avoid making every creative a miniature version of the blog article, with several paragraphs squeezed into a frame people will see on a phone.

Keep an editable master and export separate versions

Begin with a source file large enough for the intended exports, keeping the subject away from edges that later crops may remove. Preserve the editable design locally. Then create individual delivery files for the formats you actually plan to use. This avoids repeatedly compressing a social export whenever the campaign needs a new crop, corrected heading, or different platform treatment.

Useful working canvases can include square, portrait, and landscape versions. Their exact dimensions depend on the destination and format; they are production choices rather than a promise that every network accepts the same settings. Do not enlarge a small source photograph just to match an arbitrary template. Find a stronger source or redesign around the image's real resolution instead of hiding softness behind extra pixels.

Use Pinterest's specification as a concrete example

Pinterest's business specifications recommend a 2:3 ratio, such as 1000 by 1500 pixels, for standard image ads, which can also generate organic impressions. The same specification identifies PNG or JPEG as the file types for that format and warns that taller images can be cut off in feeds. This is a useful destination-specific example, not a size rule for every social post.

For a fictional article about calendar audits, a vertical Pin might contain a clear calendar illustration and the short heading “Find duplicate posts.” Put the essential information where it survives normal presentation and remains readable at mobile size. Do not assume that specifications for one Pinterest format establish the requirements of another, or that an image accepted through native publishing will behave identically through every third-party workflow.

Crop around meaning rather than the frame

When adapting a landscape design to a portrait format, inspect what the crop removes. A crop that keeps the person's face but loses the product they are demonstrating may destroy the image's purpose. A calendar screenshot that retains the date but removes the duplicate entries no longer supports an audit tutorial. Change the layout when necessary instead of forcing the original composition into every shape.

A practical method is to mark the essential region in the master: subject, necessary context, and any short explanatory line. Produce each crop and compare it with that region. If the essential content cannot fit naturally, use another photograph or rebuild the graphic. Consistent branding comes from recognizable visual choices, not from preserving identical geometry when the destination asks for a different composition.

Choose a file format based on the image and destination

JPEG is often a useful starting point for photographs; PNG can be helpful for graphics with crisp text or transparency where the destination accepts it. Inspect the exported result rather than treating the extension as proof of quality. Fine text, thin lines, gradients, and detailed photographs respond differently to compression. The right file is the one that preserves the necessary information within the actual publishing requirements.

Keep website delivery separate from social delivery. A WebP image may be appropriate for a blog's performance goals, while a particular social format calls for JPEG or PNG. Do not assume a web-optimized featured image is automatically the best social upload. Maintain the approved master and create the delivery version needed for each channel, recording those versions clearly in the campaign assets.

Check color, file size and legibility together

Pinterest's specification recommends PNG with sRGB for advertisers and states that custom color profiles are unsupported. That is a useful reminder to test ordinary screen presentation rather than trusting how an image looks inside a design application. Export a standard screen-oriented version, open the actual file, and check whether colors, fine edges, and text still communicate as intended.

Compress enough to make the file manageable without damaging the message. Avoid choosing a universal size target and degrading every image until it meets it. A small photograph and a detailed chart have different needs. Inspect the image at its intended viewing size and at phone scale, then compare the compressed export against the source. If a line disappears or a label becomes fuzzy, revise the design or export settings.

Add accessibility during production

Write the image description while the creative's purpose is fresh in your mind. A useful description of the audit example might be “Two identical promotional cards appear on the same day in a weekly calendar.” That explains the meaningful relationship rather than listing every decorative element. Keep important instructions in the post's text too, especially when a graphic contains information a reader needs to act on.

OnlySocial documents adding alternative text by selecting an image in the composer, choosing Add ALT Text, entering a description, and saving. Its guide conditions publishing that information on platform support. Prepare the description for each meaningful image and verify delivery on the actual destination; do not claim that saving the field establishes identical accessibility across all connected networks.

Match the media to the platform version

Select the destination accounts in the composer and use the documented post-version workflow to adapt both caption and media. A short text observation and a graphic tutorial may share a subject while needing different visual support. Review each version independently. A beautiful Pin image attached accidentally to the wrong account is still a publishing error, even if the source campaign and affiliate destination are correct.

Look for text-image contradictions as part of this pass. If the caption says “three checks” while the graphic displays five steps, decide which version is correct before scheduling. Check dates, language, account names, disclosures, and the promised next action. Correcting the design only in the local master is insufficient; export and attach the revised file, then reopen the saved draft to inspect it.

Use a small publishing test before scaling

For a new format or unfamiliar account, validate one complete draft before preparing a large batch. Confirm the correct file, aspect ratio, visible crop, caption, destination, and accessibility fields. After an authorized test publication, inspect the native result on a phone-sized screen. That reveals presentation issues a desktop preview may not show and gives you a better production reference for the remaining campaign.

Record successful settings as a dated campaign template, with the specific destination and format attached. Recheck that template when platform requirements or your account connection changes. A repeatable image workflow should reduce repeated decisions while preserving the judgment that each creative needs: a clear job, appropriate composition, readable export, and verified appearance where the audience actually encounters it.
