Frequently Asked Questions

Yes, 100% free. No trials, no "freemium" tiers, no paywalls. We monetize through ethical, non-intrusive Google AdSense ads. You will never be asked for a credit card or subscription. All core features are and will always remain free.

No! We deliberately avoid forcing signups. All tools are accessible instantly without any login, email, or personal information. Your privacy is our priority.

Your data never leaves your device. All calculations and file processing happen client-side in your browser using JavaScript. We cannot see, access, or store your financial data, images, or PDFs. You can verify this by opening your browser's Developer Tools and checking the Network tab—there are no upload requests.

Absolutely! All our tools are fully mobile-optimized and work seamlessly on iOS (iPhone/iPad) and Android devices. No app installation needed—just open the website in your mobile browser (Chrome, Safari, Firefox).

Yes! Marketing agencies, consultants, and businesses use our tools daily with clients. The only restriction: you cannot rebrand our tools as your own product or embed them in a competing website without permission.

ROAS measures ad efficiency: Revenue ÷ Ad Spend. It ignores other costs.ROI measures overall profitability: (Revenue - All Costs) ÷ All Costs. ROAS is for marketing optimization; ROI is for business decisions.

No. ROAS is a ratio that cannot be negative. If you spend $1,000 and make $0 revenue, your ROAS is 0. If you make $200, your ROAS is 0.2x (20%), meaning you lost $800. Anything below 1.0x means you're losing money.

After calculating your results, click the "Download Report" button. This generates a professional PDF report with your ROAS score, profit metrics, and breakdown—perfect for sharing with team members or clients.

Yes! The "Product Cost" field should include everything you pay per sale: product cost, shipping to customer, packaging materials, transaction fees (Stripe/PayPal), and any other variable costs. This gives you accurate profit calculations.

Yes, we use live data from financial institutions updated every few minutes. However, the rate you actually receive from your bank or transfer service may differ slightly due to their markup (typically 1-5% above the mid-market rate we show).

We show the "mid-market rate"—the real exchange rate banks use between themselves. Your bank adds a markup (profit) on top of this. Google's rates update less frequently. Minor differences (0.1-0.5%) are normal. Always confirm with your bank before large transfers.

Not currently. Our tool shows real-time rates only. For historical data, check XE.com or OANDA. We're considering adding this feature in Q3 2026.

In the "Target Max Size" field, type 0.05 (because 50 KB = 0.05 MB). The tool will automatically compress the image to meet this target. Always preview before downloading to ensure quality is acceptable.

It depends on the target size. For passport photos compressed to 50KB, facial features remain sharp. Below 20KB, some blur is inevitable. If quality is poor, increase the target size slightly. Most exam portals specify a maximum (e.g., "under 50KB"), not an exact size.

Yes! We support JPG, JPEG, PNG, and WEBP formats. However, PNG files (especially with transparency) compress less efficiently. For photos, we recommend converting to JPG first for better size reduction.

No limits! Compress as many photos as you need. Since processing happens locally in your browser, there's no server queue or usage caps.

Upload all your images (certificates, ID proofs, etc.), then set the "Target Size" to 2 (meaning 2 MB). The tool will automatically compress each image before creating the PDF to meet your size requirement. For safety, aim for 1.8 MB if the portal says "under 2 MB."

Yes! There's no page limit. However, keep in mind that more images = larger file size. If you need to stay under a specific size limit (e.g., 2 MB), you may need to split into multiple PDFs or reduce image quality more aggressively.

Images are arranged in the order you select them. When choosing files, click them in the correct sequence. On Windows/Mac, hold Ctrl/Cmd and click each file one by one in order. On phones, select one at a time. Alternatively, rename your files (01-Photo.jpg, 02-Signature.jpg) so they auto-sort correctly.

Not currently. Most government portals don't require password-protected PDFs (in fact, they often reject them). If you need encryption for business purposes, use Adobe Acrobat or Smallpdf after downloading your PDF from our tool.

Partially. The Image Compressor and PDF Converter work offline once the page loads (because they process locally). However, the Currency Converter requires internet to fetch live exchange rates. The ROAS Calculator works fully offline.
