1converter is a free online file conversion platform that supports over 243 file formats across 13 categories, including documents, images, videos, audio, and archives. Built for both casual users and professionals, it processes conversions server-side using optimised engines — LibreOffice for documents, FFmpeg for media, and ImageMagick for images. No software installation is required. Files are uploaded over HTTPS, converted on secure cloud servers, and the output is available for download immediately. The service handles everything from simple JPG-to-PNG conversions to complex multi-step format chains, making it suitable for individuals, teams, and automated workflows alike.

Yes, 1converter offers a permanently free tier with up to 10 conversions per day and a 10 MB file size limit per file — no credit card required. For heavier workloads, paid plans start at $9.99 per month (Starter) and include up to 50 MB files and 1,000 API requests monthly. The Professional plan ($29.99/month) raises the limit to 500 MB and 10,000 API calls, while the Business plan ($99.99/month) offers unlimited conversions and file sizes. Annual billing provides up to 20% savings across all paid tiers.

No account is needed to start converting files. Guest users can convert up to 10 files per day with a 10 MB file size cap. Creating a free account unlocks additional benefits: a persistent conversion history so you can re-download past results, batch processing of multiple files at once, integration with cloud storage providers (Google Drive, Dropbox, OneDrive), and the ability to generate shareable download links with optional password protection. Account registration takes under 30 seconds and supports email/password, Google, and GitHub sign-in methods.

1converter supports 243 file formats across 13 categories. Images: PNG, JPG, WebP, SVG, HEIC, AVIF, TIFF, BMP, GIF, ICO, and 20+ RAW camera formats. Documents: PDF, DOCX, XLSX, PPTX, ODT, RTF, TXT, EPUB, HTML, and more. Video: MP4, AVI, MKV, MOV, WebM, FLV, WMV, and 15+ others. Audio: MP3, WAV, FLAC, AAC, OGG, OPUS, M4A, and more. Archives: ZIP, RAR, 7Z, TAR, GZ, ISO, and 20+ additional archive types. Vector graphics: SVG, PDF, AI-compatible formats. The full format list is available in the API documentation.

Conversion speed depends on file size, format complexity, and server load. As a benchmark: a 1 MB image converts in under 2 seconds; a 10 MB PDF converts in 3–8 seconds; a 100 MB video file typically takes 30–90 seconds. Document conversions (e.g., DOCX to PDF) are generally faster than video transcoding because they require less computational processing. Files are queued using Redis for reliable background processing, and real-time progress is streamed via Server-Sent Events (SSE) so you always see the current status. Peak server load can occasionally add 10–20 seconds to larger jobs.

Maximum file size depends on your plan. Free (guest) users are limited to 10 MB per file. Starter plan ($9.99/month) allows up to 50 MB. Professional plan ($29.99/month) supports up to 500 MB per file. Business plan ($99.99/month) has no file size limit and is designed for large video files, high-resolution images, and bulk document processing. For context, a typical HD video at 30 minutes runs around 500 MB at standard compression. Files above 200 MB are uploaded using chunked transfer encoding to ensure reliability on slower connections.

Yes. Batch conversion is available on all paid plans (Starter, Professional, and Business). You can upload up to 50 files in a single batch job, select a target format, and convert all of them simultaneously. Each file in the batch is processed independently, so a failure in one does not affect the others. Batch results are packaged into a single ZIP archive for convenient download. Batch jobs are also accessible through the REST API, allowing developers to automate bulk file conversion workflows programmatically with full status tracking per file.

Security is a core design principle of 1converter. All file uploads and downloads are transmitted over HTTPS using TLS 1.2 or higher, ensuring data is encrypted in transit. Files are stored in isolated cloud storage (Cloudflare R2) with access controlled via cryptographically random tokens — no sequential or guessable IDs are used. Converted files are automatically purged from storage within 24 hours. The platform does not share files with third parties, does not train AI models on uploaded content, and passes all server-side security headers including HSTS, Content-Security-Policy, and X-Frame-Options.

1converter uses temporary storage exclusively for the purpose of delivering your converted file. Files are retained on Cloudflare R2 storage for a maximum of 24 hours from the time conversion completes, then deleted automatically by a scheduled cleanup worker. No backups of user files are created. Authenticated users can optionally extend retention by saving files to their account history, but this is never done automatically without consent. Database records store only metadata (file name, size, format, status) — the actual file content is never written to the relational database.

No. Each converted file is assigned a cryptographically random 64-character token as its download URL. This token cannot be guessed through brute force — the probability of a random match is astronomically low. By default, files are private and only accessible to the user who created them. If you choose to share a file using the built-in share link feature, you can optionally add a password requirement and set an expiry time or maximum access count. Share links can be revoked at any time from your account dashboard, immediately invalidating all active access.

Yes, 1converter is fully GDPR compliant. User data is stored on PostgreSQL servers in the EU (eu-west-2 region via Neon). We collect only the minimum data necessary to operate the service — email address, hashed password, and conversion metadata. We do not sell, rent, or share personal data with third parties. Users have the right to access, correct, export, and permanently delete their account data at any time from the Settings page. Data deletion requests are processed within 30 days as required by GDPR Article 17. A complete privacy policy is available at /privacy.

Yes. 1converter provides a comprehensive RESTful API with 450+ endpoints covering file conversion, batch processing, status polling, share link management, and cloud storage integration. The API uses JSON request/response format, supports HTTP multipart uploads for binary files, and authenticates via API keys passed in the Authorization header. Real-time conversion progress is available via Server-Sent Events (SSE). API access is included with Starter, Professional, and Business plans. Full OpenAPI documentation with request/response examples is available at /api-docs. Rate limits and file size caps match your plan tier.

Sign up for a Starter, Professional, or Business plan, then go to your account dashboard and click on the API Keys section in the left sidebar. Click "Generate New Key", give it a descriptive name (e.g., "Production App"), and optionally restrict it to specific IP addresses or API scopes. The key is shown once at creation — copy it immediately and store it securely (e.g., in an environment variable or secrets manager). You can create up to 10 API keys per account and revoke any key instantly if it is compromised. Each key carries the same rate limits as your plan.

Rate limits are applied per API key on a rolling monthly basis. Free accounts receive 100 API requests per month with a 10 MB file size limit per request. Starter ($9.99/month) provides 1,000 requests/month and 50 MB file limit. Professional ($29.99/month) allows 10,000 requests/month and 500 MB per file. Business ($99.99/month) has unlimited requests with no file size restriction. In addition to monthly quotas, all tiers are subject to a burst limit of 60 requests per minute to protect server stability. Exceeding the burst limit returns HTTP 429 with a Retry-After header.

Yes, there are no long-term contracts. You can cancel your subscription at any time from the Billing section of your account dashboard with a single click — no need to contact support. After cancellation, your paid plan remains active until the end of the current billing period; you will not be charged again. Your account reverts to the free tier automatically at renewal. Conversion history, API keys, and account settings are preserved even after downgrade. If you cancel within 14 days of a new subscription or upgrade, you are eligible for a full refund under our money-back guarantee.

Yes. 1converter offers a 14-day money-back guarantee on all new subscriptions and plan upgrades. If you are not satisfied for any reason, contact our support team at support@1-converter.com within 14 calendar days of the charge and we will issue a full refund to your original payment method — no questions asked. Refunds are typically processed within 5–10 business days depending on your bank or card issuer. The 14-day window applies per subscription transaction; it does not reset on renewal. Partial refunds for unused days are not available outside the guarantee window.

1converter accepts all major credit and debit cards — Visa, Mastercard, American Express, Discover, and UnionPay — as well as PayPal. All payment processing is handled by Stripe, a PCI DSS Level 1 certified payment processor, which means your card details are never stored on our servers. For annual subscriptions, the full yearly amount is charged upfront at a discounted rate. Invoices and receipts are generated automatically and emailed to your billing address after each successful charge. Enterprise customers can request bank transfer (ACH/SEPA) payment options by contacting our sales team.
