Website Mockup Sharing Tool: What to Check Before You Send the Link
10/11/2026 · 6 minute read · By Swelik
A quality and delivery checklist for sharing long website mockups, with practical checks for resolution, mobile viewing, revisions and privacy.
A website mockup sharing tool turns an exported design into a browser destination that a client can open and review. The goal is simple: show the design clearly, make the current revision easy to find and keep owner controls separate from the link you send out.
The upload itself is only part of that job. The source needs enough detail, the viewer needs to preserve the layout and the handoff needs a clear review question. Before sending a link, check the whole path from design export to the client's screen.
Choose a sharing surface for the actual decision
Use a mockup when the client needs to review appearance, message and hierarchy. A complete page export is useful because it preserves the relationship between sections. Cropped screenshots sent in separate messages can make it difficult to understand the full flow from headline to final action.
If the client must test a multi-screen interaction, use a prototype alongside the visual preview. If they must submit a real form or place a test order, use the implementation. A sharing tool can present an artifact well, but it cannot supply functionality that the artifact does not contain.
Inspect the source before uploading
Open the exported file locally at the size you expect the client to inspect. Check small labels, thin icons, paragraph text and any image with fine detail. If these are already blurry in the source, uploading the file will not recover the missing information.
Avoid exporting a narrow thumbnail and expecting it to become sharp when stretched across a desktop display. Keep the intended viewing width in mind. Also remove stray design-tool guides, off-canvas objects and accidental blank space before export so the client sees the intended composition.
Understand image, PDF and HTML tradeoffs
PNG, JPEG and WebP are raster formats, so their visible detail depends on the pixels in the file. JPEG can introduce visible artifacts around sharp text when compressed heavily. PNG or an appropriately prepared WebP can be a useful choice for interface exports, but compare the result rather than relying only on the extension.
A PDF can contain vector text, vector shapes and embedded raster images. It is not automatically sharp at every zoom level. A low-resolution screenshot placed inside a PDF remains a low-resolution screenshot. HTML can preserve live text and layout, but its images, fonts and stylesheets must be available in the preview environment.
For a deeper format decision, see PNG, WebP, PDF or HTML for website mockups. Choose the format that preserves the work you actually have, then inspect the shared result.
Check the entire long page
Do not stop after the hero section loads. Scroll to the middle, pricing area, contact section and footer. Confirm that nothing is cropped and that the spacing matches your export. Look for an unexpectedly large blank region, a missing page or a file that has been rotated during export.
For PDFs, inspect every relevant page. For static HTML, check pictures and fonts after the initial layout appears. External assets can fail independently of the HTML document. A successful project creation message means the upload completed, not that every remote image is guaranteed to load forever.
Test what mobile viewing means
An image of a desktop design can scale down to fit a phone, but that does not turn it into a mobile design. The client may need to zoom to inspect small text. If mobile layout is part of the decision, share a separate mobile export or an appropriate responsive implementation.
Use an actual phone when practical. Check that the preview opens, the toolbar stays usable and the client can reach the bottom of the design. Explain whether the artifact represents desktop appearance, mobile appearance or a responsive HTML layout. This avoids approving a desktop screenshot as if it proved the mobile experience.
Keep public and management links separate
Swelik creates a public preview destination and a private management link. Send the public URL to the client. Save the management URL for yourself because it allows changes such as replacing or deleting the preview. Label the two links clearly in your own project notes.
An unlisted public preview can still be viewed by someone who obtains its URL. It is not a password-protected workspace. Use a different access arrangement if the project requires restricted identities or confidential delivery. Check the preview's expiry date and retain your original files outside the review link.
Name the project for the client
Use a recognizable project title, such as “Acme services homepage,” rather than an internal export name containing random suffixes. Keep revision details in the review message or your own archive. The title should help a client who has several tabs open identify the correct design.
Before sharing, open the public URL in a fresh browser session. Confirm that it shows the correct project and not an owner dashboard. Copying the wrong link is a small mistake with a large effect on the review experience.
Replace revisions without scattering links
When you update the design, use the management page to replace the mockup. Swelik keeps the public URL unchanged. Send a short message saying the new revision is available and list the meaningful changes. Ask the client to reload an already-open preview before responding.
Retain the previous export in your project archive. A stable review destination is convenient, but an archived revision can still matter when comparing decisions or preparing the final handoff. Separate the current review link from your long-term record of the project.
Include a focused request with the link
Try a message such as: “Please review the headline, service order and enquiry section. The staff photographs are temporary. Send one consolidated response by Tuesday, identifying the section and the outcome you want.” This tells the client how to help.
Avoid presenting every update as final if important decisions remain open. A clear review stage makes feedback more useful and prevents a placeholder from being mistaken for an approved asset. Our feedback workflow guide covers turning those comments into revisions.
A final pre-send check
Confirm the title, correct artifact, full-page rendering, readable detail and usable public URL. Check mobile access, note any provisional elements and save the private management link. Then include the review scope and deadline in the message. These checks take less effort than untangling a review of the wrong file.
If the preview differs from the source, resolve that difference before requesting approval. The client should assess the intended design, not a rendering problem that the designer already knows about.
Frequently asked questions
Will a sharing tool make a low-resolution mockup sharper?
No. A viewer can preserve and display the available detail, but it cannot restore detail that was lost during export. Start by checking the original at the intended display size.
Should I send the source file instead?
Send source files when the handoff requires them. For a focused review, an exported preview can keep attention on the deliverable. Source delivery and client presentation are separate tasks and can use different destinations.
Can one link stay current through revisions?
Yes. Swelik's replacement workflow keeps the public URL while updating the mockup. Tell reviewers when a new version is ready and keep your own dated exports. Create a preview once your export passes the checks above.
