The safest social-image workflow is one untouched archival master followed by independent crops for each placement. Crop for composition first, resize once at the end, sharpen at delivery size, and export each derivative from the master—not from yesterday’s compressed square.
Preserve an archival master
Keep the largest available file with editable layers or lossless data. Do not flatten, sharpen aggressively, or convert it repeatedly. Record:
- pixel dimensions;
- color profile;
- source and edit provenance;
- creation date and version;
- whether texture was generated, scanned, photographed, or painted digitally.
Name it master, not final. “Final” invites someone to overwrite it when a platform asks for a smaller file.
Correct the image before multiplying it
Do global corrections on the master or a non-destructive working copy:
- horizon and geometry;
- dust or accidental artifacts;
- overall tonal balance;
- color cast;
- local distractions near the focal point;
- blank or damaged edge pixels.
For a simple upload-and-edit pass, FreePhotoEditor fits this preparation step before you create channel-specific derivatives. Keep a separate master because AI edits or object removal can alter neighboring texture and should be reviewable against the source.
Crop by visual function
Do not center-crop automatically. Identify:
- primary subject;
- directional gesture or gaze;
- supporting shape;
- quiet space that gives the painting rhythm;
- edge details that can be sacrificed.
A square often needs the focal point moved inward. A portrait crop can preserve a standing figure or upward gesture but may remove horizontal context. A landscape crop can keep environment while shrinking a face. Make a compositional decision for each.
Use crop overlays on the master and save them as named guides. Never stretch one ratio into another.
Practical derivative set
Platform interfaces change, so confirm specifications at release. As a durable working set:
| Derivative | Working ratio | Composition job |
|---|---|---|
| Vertical feed | 4:5 | preserve figure and downward/upward gesture |
| Square | 1:1 | make one subject unmistakable |
| Landscape | 16:9 or 1.91:1 | include environment or use as link/thumbnail art |
| Tall discovery image | 2:3 | retain vertical story and texture |
LinkedIn says photo ratios can range from 3:1 to 4:5 and may be centered and cropped beyond its display limit. YouTube recommends 16:9 for custom thumbnails. Pinterest recommends 2:3 for standard images and warns that taller ratios may be cut off in feeds. Those differences are why a universal export is false economy.
Resize once
Cropping changes the canvas. Resizing changes the pixel count. Keep them separate.
Adobe’s resizing guidance distinguishes changing dimensions from resampling image data. For web delivery, resampling is expected; the goal is to do it intentionally from the highest-quality source.
Recommended sequence:
- duplicate the master or create an export composition;
- apply the target crop;
- resize to the delivery pixel dimensions;
- inspect at 100% and at actual small display size;
- apply restrained output sharpening;
- export to the chosen format;
- reopen the exported file for a final check.
Do not resize to 1080 pixels, discover the crop is wrong, crop again, and enlarge for another platform. Every resampling pass throws away or invents information.
Protect painterly texture
Fine canvas grain, dry-brush edges, watercolor blooms, and impasto highlights can turn into halos or noise after downsampling and compression. Review three zones:
- the focal edge, such as eye against skin or roof against sky;
- a mid-frequency texture, such as cloth or foliage;
- a quiet gradient, such as wall, paper, or open sky.
If the focal edge is mushy, add light output sharpening. If texture crawls or sparkles, reduce high-frequency detail before export or use a slightly larger file. If gradients band, avoid repeated lossy saves and test another format.
Choose JPEG or PNG by content
JPEG is usually efficient for paintings, photographs, and continuous-tone texture. Export once at a visually tested quality; do not resave the JPEG repeatedly.
PNG is useful for transparency, sharp flat graphics, and text-heavy overlays. A full painterly image may be unnecessarily large as PNG.
Keep the color behavior predictable. For general web delivery, use a broadly supported RGB profile and preview the exported file in a browser. Do not assume the editing application’s dark canvas and wide-gamut preview match every phone.
The thumbnail test
Preview each derivative at 96 pixels wide and ask:
- Is the subject still identifiable?
- Does the highest contrast support the focal point?
- Did texture become noise?
- Is there accidental edge tension?
- If text exists, can the first line be read?
A social image is not a miniature gallery wall. It is a small invitation to look more closely. The crop must establish one clear reason to stop.
Export manifest
Keep a tiny table beside the files:
| Filename | Source version | Crop | Pixels | Format | Use |
|---|---|---|---|---|---|
harbor-v07_4x5.jpg | v07 | portrait | 1600×2000 | JPEG | vertical feed |
harbor-v07_square.jpg | v07 | square | 1600×1600 | JPEG | general post |
harbor-v07_16x9.jpg | v07 | landscape | 1920×1080 | JPEG | thumbnail |
harbor-v07_2x3.jpg | v07 | tall | 1600×2400 | JPEG | discovery feed |
The manifest prevents mystery exports and makes later replacement possible when a platform changes its display.
Final release checklist
- Archival master is separate and untouched.
- Each derivative was cropped from the master.
- Focal point and key gesture survive the target ratio.
- Resize happened once, after crop.
- Texture was inspected at 100% and thumbnail size.
- Format matches continuous tone, transparency, and text needs.
- Export was reopened and checked in a browser.
- Filename records source version and ratio.
The best export workflow is boring and reversible. That is exactly what protects the painting while the delivery channels keep changing.
