How to Resize and Prepare Upwork Project Catalog and Portfolio Images Before Upload

A careful upload workflow for turning a permitted work sample into a clean Upwork Project Catalog or portfolio delivery copy.

Start with a real, permitted work sample. Remove risky elements. Export one clear delivery copy. Compress lightly. Preview the image the way a client will see it. That sequence is safer than resizing first and trying to fix problems later.

This workflow applies to legitimate Upwork Project Catalog gallery images, portfolio thumbnails, case-study screenshots, process diagrams, and PDF work sample covers.

Official Upwork guidance summarized: Upwork says Project Catalog images should be JPEG or PNG, under 10 MB, 4:3, no larger than 4000 pixels in width or height, and sharp at 1000 × 750. Upwork’s portfolio guidance also recommends 1000 × 750 for portfolio images. Review the current Project Catalog image upload guidance before submitting.

The 12-step Upwork image preparation workflow

1. Choose the Upwork use case. Decide whether the image belongs in Project Catalog, a portfolio item, a case study, a screenshot, or a PDF cover.
2. Confirm the work is yours or permitted. Do not upload private client work unless you have permission to share it.
3. Remove contact information. Delete email, phone, personal website, QR code, username, social handle, or direct contact instructions.
4. Remove risky references. Remove unauthorized logos, watermarks, competitor references, and unrelated platform elements.
5. Choose the correct image role. Gallery, thumbnail, case study, screenshot, process visual, and PDF cover should not all use the same crop.
6. Crop around the relevant service proof. Keep the deliverable or result near the center so the preview does not cut it away.
7. Choose JPG or PNG. Use JPG for rich mockups and PNG for UI screenshots, charts, typography, flat graphics, and crisp owned-logo edges.
8. Resize toward current Upwork guidance. Plan around 1000 × 750 where appropriate, keep within maximums, and verify the live upload screen.
9. Compress lightly. Shrink the delivery copy without damaging UI labels, dashboards, charts, icons, or proof details.
10. Preview like a client. Check desktop and mobile readability, crop, text density, and relevance.
11. Add the image to Upwork. For Project Catalog, add gallery images in the order you want them to appear because Upwork says added images cannot be reordered.
12. Review the whole project. Check accuracy, professionalism, privacy, category fit, and policy-safe wording before submitting.

Workflow table for quick checking

Stage	Action	Pass condition	Stop if
Use case	Choose Project Catalog, portfolio, screenshot, diagram, or PDF cover.	The image role matches the client-facing goal.	You are trying to make one export serve every placement.
Permission	Confirm ownership or sharing permission.	The sample can be shown publicly or has safe sample data.	It contains confidential or private client material.
Cleanup	Remove contact details, unauthorized logos, watermarks, and unrelated references.	The image is platform-safe and service-specific.	It includes off-platform contact or misleading claims.
Crop	Frame the proof inside a 4:3-friendly preview.	The important result remains visible at thumbnail size.	The crop hides the deliverable or makes text unreadable.
Export	Choose JPG or PNG and create a delivery copy.	The file is lighter but still readable.	Compression blurs UI text, dashboard labels, or diagram edges.
Preview	Inspect the upload screen before publishing or submitting.	The image is clear, accurate, professional, and relevant.	It looks clickbait-like, crowded, blurry, or mismatched.

Keep source files separate from upload copies

Your source design, full screenshot, editable mockup, PDF file, and Upwork delivery image should not be the same file. A delivery copy is allowed to be cropped, resized, and compressed for one placement. The source file should remain untouched in case you need to rebuild a sharper version later.

No unsafe shortcuts: Do not add fake reviews, fake credentials, fake client results, direct payment instructions, private dashboards, or contact details to make a Project Catalog image look more persuasive.

Compress only after the content is safe

Compression is the final polish step, not the first step. A smaller file is not useful if the image contains private information, unauthorized logos, unrelated service examples, or text so tiny that the client cannot understand the offer.

Final delivery copy: After removing contact information and checking that the image matches the Upwork service, create a lighter JPG or PNG delivery copy with ConvertiImage, then preview the Project Catalog gallery or portfolio item before submitting.

Troubleshooting: If the preview still looks weak, use the blurry and cropped Upwork image diagnostic guide.

Format help: If you are unsure about JPG, PNG, portfolio dimensions, or work-sample roles, read the Upwork image size and JPG vs PNG guide.

FAQs About Preparing Upwork Images Before Upload

Remove private details first. A perfectly sized image is still unsafe if it exposes client names, account data, contact details, or confidential information.

Only after one representative sample passes the preview check. Different roles may need different crops or file formats.
